Startups rarely begin with certainty. They start with curiosity, risk, and often, no playbook.

For [Oleh Shkinder](http://linkedin.com/in/oleh-shkinder-38228315b), that beginning came during a turbulent time, building a fintech platform from Ukraine as war loomed, and resources were stretched thin. What started as a side project eventually evolved into *Investables*, a platform for fractional ownership of physical collectibles, and ultimately became a startup acquired by U.S.-based fintech company *Stockpile*.

Today, Oleh serves as the Senior Product Manager at Stockpile, where he leads product development efforts for cryptotrading, membership billing, and platform features, impacting over 1 million families across the United States. His story is one of resourcefulness, resilience, and a sharp eye for scalable, user-centric product design.

### From Ukraine to 0–1: Building Investables

In 2022, amid political uncertainty and personal risk, Oleh co-founded Investables, an investing platform giving users access to physical assets through fractional ownership. Initially launched as a retail platform, it quickly evolved into a B2B API, enabling partners to embed alternative investing into their own apps.

Working remotely under crisis, Oleh juggled multiple roles: product strategist, architect, vendor integrator, and investor liaison. The product’s value crystallized after several pivots. Oleh evolved it into a B2B infrastructure solution that enabled fintechs to introduce a new asset class to their end users seamlessly. Early pilot integrations verified the demand, leading to multiple active contract negotiations with established brokerages.

The startup’s growth caught the attention of Stockpile, a Series B fintech serving U.S. families. In 2023, Stockpile acquired Investables, a defining moment that validated not just the product but Oleh’s ability to lead under pressure.

### Making an Enterprise Impact at Stockpile

After the acquisition, Oleh took the lead on key product areas at Stockpile, directly impacting user growth, engagement, and revenue.

In his first year, he delivered trading, crypto, and portfolio capabilities that boosted retention by over 23% and increased user satisfaction by 30%. Through disciplined, data-driven experimentation aligned with the company’s North Star Metric, he helped drive sustained increases in MAU and contributed materially to growing AUM.

He also introduced wallet-based billing and optimized the membership lifecycle, leading to a 23% increase in recurring revenue and stronger conversion rates across user cohorts.

By aligning engineering, design, and data teams, he consistently shipped on time through clear roadmaps and OKRs aligned with the company’s strategy.

### Strength in Structure: The Power of Process

Despite his creative energy, Oleh’s approach to product management is rooted in discipline and clarity.

*“Discipline and structure,” he says, “are the real foundations of creativity and progress.”*

This philosophy sharpened during his time at Investables, where every day required fast decisions, constant adaptation, and focused execution under uncertainty.

This mindset now influences his approach at Stockpile, guided by three key principles. First, he maintains a strong user focus, beginning with customer problems and making decisions based on data and real behavior. Second, he clarifies ambiguity by breaking down complex issues and aligning teams around the most impactful goals. Third, he influences without formal authority, communicating effectively and building trust to ensure that teams work together in the same direction.

His work reflects a structured, fast-moving approach to building products with depth and intention.

### Guiding the Next Generation at Beta University

Since mid-2025, Oleh has mentored early-stage founders at Beta University, a Palo Alto pre-acceleration program that focuses on validating ideas and preparing for fundraising.

His hands-on, data-driven approach helps teams define go-to-market strategies, spot product-market fit, and structure investor-ready metrics, grounded not in theory, but in his own journey from concept to acquisition.

### Earlier Roles: Pattern Recognition Through Experience

Before founding Investables, Oleh built a deep foundation across fintech, SaaS, crypto, and AI.

At Changeblock, he worked as a product consultant, shipping an MVP in close collaboration with the Cardano Foundation to help tokenize carbon credits globally.

At Heureka, he led a logistics SaaS (Software as a Service) used by enterprise clients, including Siemens and DB Schenker. His focus was on AI-driven optimizations that significantly reduced operational inefficiencies. He recognized that to move faster, the organization needed a new operating model, which led him to drive an agile transformation across various teams.

Subsequently, he held roles at SoftServe, where he contributed to large-scale digital transformation projects, and at Magnise, where he helped fintech clients secure significant early funding by collaborating closely with engineering to deliver high-quality products.

Each of these roles enhanced his systems thinking, data intuition, and user empathy, foundations that continue to define his approach to product leadership today.

### AI as a Strategic Advantage

Today, Oleh is leading the way in integrating AI into product development, not simply as a tool for automation, but as a creative and technical partner. He utilizes platforms like Lovable, Supabase, ChatGPT, and custom agent workflows to rapidly validate ideas, prototype comprehensive experiences, and explore new product directions. For him, AI isn’t just a shortcut; it’s a means to work more efficiently, discover new possibilities, and communicate solutions with much greater clarity.

For him, AI is not about replacing product intuition; it’s about amplifying it. He envisions a future where product managers operate more like storytellers and strategists, leveraging AI to automate mundane tasks and allocate more time to user insights, vision, and experimentation.

This is part of his broader aspiration: to modernize product management into a craft that blends technology, human understanding, and business impact.

### Build What Matters

Oleh’s personal north star isn’t velocity, it’s clarity.

*“The goal,” he says, “is not to build fast, but to build what truly matters.”*

That focus shows in every phase of his journey, from founder to product leader.

Living in the Bay Area has only reinforced that conviction. Surrounded by builders who think long-term and lead with depth, he’s drawn inspiration not just for work, but for life. As he says, the best builders don’t chase hype; they ship what matters.

One quote that grounds his mindset comes from Andrew Horowitz:

*“The goal isn’t to predict the future. It’s to prepare for it with clarity and discipline.”*

That lens, courage over cleverness, has shaped how he builds, leads, and mentors.

### Looking Ahead

Oleh’s next chapter is already in motion. He’s doubling down on the intersection of AI and product strategy, working to simplify complex systems into user-friendly tools, and rethinking how teams ideate, validate, and scale.

But even as the tech evolves, his foundation holds: build with purpose, lead with clarity, and stay close to the user.

From a founder under fire to a leader shaping fintech for millions, Oleh Shkinder’s story reminds us: the best products start with vision, and survive on courage.

Smart locks sit in that sweet spot between everyday habit and quiet tech upgrade. You still turn a knob, tap a code, or push a door open, but behind that simple motion is a small system of sensors, encryption, and wireless signals doing more than traditional locks ever could.   
Before choosing one, it helps to understand how the technology works and what will matter once it’s on your door. With the right information, the decision feels practical instead of overwhelming, especially when you’re looking for upgrades that bring peace of mind to your daily routine.  
<h2 id="how-smart-locks-work-in-everyday-use-">How Smart Locks Work in Everyday Use  </h2>
A smart lock uses sensors, wireless signals, and a small motor to unlock the door once it confirms the right access method. When you enter a code, tap your phone, or approach with Bluetooth enabled, the lock checks the information and responds through its smart lock mechanism. Many models offer keyless entry, which removes the need to rely on a physical key every time you come home.  
Most models use Bluetooth, Wi-Fi, or a combination of both. Bluetooth handles close-range access and helps preserve battery life. Wi-Fi enables you to check or control the lock remotely when you are away from home, introducing a level of remote access that wasn’t possible with older systems. Some systems work through a hub, which is ideal if you plan to build a larger setup with other connected devices.  
The physical hardware matters more than most people realize. A smart<a href="https://lockly.com/products/lockly-doorknob"> door knob lock</a> works best when it’s paired with a door knob that feels sturdy and moves without resistance. When the latch, hinges, and installation requirements all line up correctly, the entry feels smoother and more reliable day after day.  
<h2 id="how-smart-locks-improve-home-security-">How Smart Locks Improve Home Security  </h2>
Smart locks change how you handle those small worries, like wondering if you locked the door while rushing out. Instead of turning around or calling someone at home, you check the app and lock the door from wherever you are through a smartphone app. It takes the stress out of moments that used to interrupt your day. You can also create individual codes for guests or deliveries and remove them when they’re no longer needed, which helps keep track of spare keys and facilitates activity tracking.  
Some smart locks connect to cameras or simple door sensors to show activity at your entry. You might get a quick clip of who arrived or an alert if the door stays open longer than it should. You don’t need a full security system for this to make a difference. It’s enough to choose a lock that lets you add a few devices later, like security lighting, if you want a little more visibility.  
<h2 id="the-different-types-of-smart-locks-you-need-to-know-">The Different Types of Smart Locks You Need To Know  </h2>
Smart locks come in a few different styles, and the right choice depends on how much you want to change your door. Some models fit over your existing deadbolt, keeping the outside hardware the same, which works well if you prefer something subtle or want to continue using a key as a backup. These lighter upgrades fall under the growing category of smart door locks and blend into most door setups with ease.  
Others replace the entire lock set with a new keypad or touchscreen on the outside and a matching unit on the inside. This gives you a clean look and more control over the finish and style. There are also hybrid designs with<a href="https://python.plainenglish.io/fingerprint-authentication-system-using-deep-learning-and-minutiae-verification-fd6a8021c66f"> fingerprint readers</a>, physical buttons, or a digital lock option for a more modern feel.  
Your habits usually point you toward the right option, so think about how you like to unlock the door now. It helps to check your door’s thickness and how well it closes before buying. A lock that sticks or forces the motor to work harder won’t give you the smooth experience you expect, especially if you plan to integrate it into larger smart home ecosystems.  
<h2 id="what-installation-and-daily-use-feel-like-">What Installation and Daily Use Feel Like  </h2>
Installing a smart lock is usually straightforward. Many models fit into the same holes your current hardware uses, and the instructions guide you through each step. Alignment is the part that matters most. If the latch doesn’t line up or the door isn’t sitting square, the motor works harder than it should and may affect certain advanced features.  
After setup, the lock slips into your routine without much effort. You hand out codes instead of keys, check the door when you need to, and adjust access as schedules change. It’s a simple upgrade that removes several small hassles you’ve dealt with for years, especially once it connects smoothly with other smart home devices you already use.  
<h2 id="features-that-make-a-real-difference-">Features That Make a Real Difference  </h2>
Smart locks come with long feature lists, but only a few matter in everyday use. Auto-lock and auto-unlock are two of the most practical because they handle the quick moments you don’t want to think about. Battery life also deserves attention. A reliable lock warns you early when power runs low and gives you a simple backup, whether that’s a key or a quick tap of a 9V battery to bring the keypad back to life.  
Compatibility can make the lock feel smoother to use. If you already rely on a<a href="https://www.forbes.com/councils/forbestechcouncil/2021/12/09/the-psychology-of-voice-technology-building-a-better-voice-assistant-for-everyone/"> voice assistant</a> or other smart home devices, choosing a lock that works with them keeps everything in one place. You avoid juggling apps and get small perks, like having the door lock when the lights turn off.  
<h2 id="in-conclusion-">In Conclusion  </h2>
A smart lock gives your entry a smoother feel and takes a few small worries off your plate. You gain clearer access, better control, and a door that works with you, rather than slowing you down. Once you know how these locks function and what features matter, choosing one becomes easier. If you want a setup that fits your routine and keeps things simple, a smart lock is an upgrade that makes everyday life run a little better.

How Do Smart Locks Work? Everything You Need To Know Before Buying One

Frictionless design represents a transition toward digital products that grant you immediate access with minimal interruption, with this metamorphosis gaining remarkable momentum in 2025 as user expectations continue rising. You’ve likely become accustomed to streaming a movie in seconds, authenticating with a quick biometric scan and moving through digital tasks without confronting confusing pathways or long forms. Companies across industries have responded by removing unnecessary steps from onboarding flows, simplifying logins through passkeys and WebAuthn standards and redesigning interfaces around predictable micro-interactions that feel supportive rather than disruptive.

As these practices spread, frictionless UX has started shaping how you and others engage with tools across entertainment, healthcare, education and finance, creating a standard where ease of entry signals credibility. In fact, almost 40% of companies worldwide are now deploying some form of passwordless authentication, a significant rise that shows how closely ease and trust are now intertwined. This broader cultural embrace of immediacy demonstrates how convenience, trust and loyalty influence your experience as a user, influencing everything from product perception to long-term satisfaction.

## Why anticipating user behavior defines modern UX

This pattern is reinforced by strong evidence: passwordless adoption has climbed rapidly, with major companies reporting far higher success rates when moving away from traditional credentials. As expectations increase, frictionless UX is becoming a baseline rather than a luxury, influencing how users judge reliability, trustworthiness and overall brand quality. For designers, this means paying close attention to what feels natural to you and establishing entry points that remove hesitation while still maintaining a strong security posture. 

Because you experience countless interfaces every day, your tolerance for friction continues shrinking, pushing businesses to rethink what “usable” truly means. Instead of expecting you to adapt to rigid structures, modern platforms are moving toward flows that anticipate how you think, what you look for and where confusion might arise. This emphasis on anticipation is helping companies construct climates that feel welcoming, intuitive and capable of responding to your needs in real time.

## Why instant access drives engagement, trust and retention

Instant access serves as a central driver of user satisfaction, particularly if you rely on speed and clarity to feel confident about a new product. When an app launches without delay, when checkout requires just a tap or when authentication happens through biometrics, the experience feels like it matches your pace and priorities. Businesses are highly motivated to meet this demand because small improvements in access speed often translate into noticeable increases in conversion, retention and long-term loyalty. As digital competition intensifies, instant access has become one of the simplest and most measurable ways to create a positive first impression.

Industry research highlights that traditional passwords lead to abandoned sessions at striking rates, while systems powered by device-based cryptographic keys or passkeys offer stronger security alongside a smoother flow. As 2025 progresses, companies in finance, health, e-commerce and entertainment continue adopting these methods to reduce onboarding friction and strengthen security without overwhelming you. This widespread push toward instant access reflects a deeper shift in user expectations: people expect digital products to adjust to their behavior, preferences and context. Today, frictionless UX supports that expectation by making every interaction feel purposeful, fluid and aligned with how you naturally navigate digital spaces.

## How authentication shapes frictionless experiences

Authentication is central to frictionless UX, as users increasingly expect stronger security alongside faster access. Passwordless methods, such as biometrics, passkeys and security keys, remove the frustration of remembering passwords. Passkey-based systems achieve high login success rates, outperform legacy methods and reduce support costs, creating backdrops where you feel secure without sacrificing speed. This shift impacts many sectors, including online gaming and comparison platforms, where smooth access is essential to your comfort and trust.

In this context, the evolution of casino comparison sites illustrates the value of frictionless entry. In illustration, [Kasinoranking.com](https://www.kasinoranking.com/) has grown steadily since 2018 through simple navigation, editorial-driven content and a layout built to help players like you find trustworthy casinos without friction. Its team has expanded alongside rising demand for cleaner, faster digital experiences, showing how intuitive authentication and well-structured pathways strengthen engagement. As frictionless login becomes more common across industries, you increasingly expect to reach the content or service you want in seconds, reinforcing the idea that speed and trust now go hand in hand.

## Broader product flows shaped by frictionless thinking

Frictionless thinking shapes entire product journeys, prompting designers to remove obstacles that slow or confuse you across multiple touchpoints. Micro-interactions, like gentle animations, responsive buttons or brief confirmation cues, signal that the system works with you, building confidence and strengthening your connection to the product. Human-centered AI enhances this by adapting flows to your behavior, presenting relevant actions at the right moments and reducing unnecessary friction.

Inclusive design is another key development, supporting [instant access for users ](https://plainenglish.io/blog/how-to-ensure-your-website-is-fully-accessible-a-developer-s-guide)with diverse abilities, devices or technical familiarity. Emerging authentication research explores solutions for users with low vision, simplifying access without compromising independence or safety. These efforts reflect a broader trend toward universal, adaptable UX, where clear, logical interactions benefit everyone. As products develop, they increasingly rely on these subtle design choices to maintain your trust and deliver experiences that feel effortless.

## End Note: Balancing convenience, security and long-term user expectations

The move toward instant access introduces important challenges, especially when designers must balance convenience and security in a world where digital threats continue evolving. While frictionless UX [emphasizes speed](https://uxplanet.org/unlocking-growth-through-ux-research-f47be992386f), certain situations still benefit from intentional pauses, such as financial transfers or account changes, where confirmation protects you from mistakes or fraud. Designers also must consider users who cannot rely on biometrics or the latest device capabilities, making strong and thoughtful fallback methods essential.

The rapid rise of behavioral and cryptographic authentication technologies is sculpting future expectations, and these systems need careful implementation to avoid making you feel monitored or restricted. The goal is to create experiences that feel natural, supportive and secure each time you interact. As connected devices multiply, expectations for instant access keep rising, pushing companies to refine their approach. Frictionless UX meets these expectations by removing barriers, reinforcing trust and creating a fluid, human-centered relationship between you and the products you use.

Top 5 JavaScript Frameworks to Watch in 2026

![](https://cdn-images-1.medium.com/max/1600/0*nxMFmNThOOlYjSVp)

Debugging is not just a part of coding -it’s where most of us spend **half our development time**.
Late-night bug hunts, coffee gone cold, staring at the same line of code for hours -we have all been there.
That’s why the right **debugging tools** can save hours, protect your sanity, and make you a faster, more confident developer.

In this post, I am sharing the **10 debugging tools every developer should know**, with **pros, cons and how I have used them in real projects**.

[Non Members-Free Read](https://medium.com/@jaydipkumarjha/top-10-debugging-tools-every-developer-should-know-c4d185d6fa5d?sk=770a5d293db7b947bf9f6c8ee1b08bed)

### 1. Chrome DevTools -The Frontend Lifesaver

Every frontend bug I have ever fixed started here. From inspecting elements to live-editing CSS, tracking network calls and stepping through JS-[**Chrome DevTools**](https://developer.chrome.com/docs/devtools?utm_source=chatgpt.com) is my go-to.

![](https://cdn-images-1.medium.com/max/1600/1*l9SlFcoJ9PYUtPek0dVk2Q.png)

Image Credit-[developer.chrome.com](https://developer.chrome.com/docs/devtools?utm_source=chatgpt.com)

**Pros:** Built-in, free, and extremely powerful.
**Cons:** Can look intimidating if you are new.
**Real-life use:** Once saved a production layout bug by hot-fixing CSS in DevTools before shipping a proper patch.

### 2. Postman -API Debugging Without Pain

[**Postman**](https://www.postman.com) is perfect for reproducing API issues without spinning up the whole frontend.

**Pros:** Great UI, lets you save and share requests.
**Cons:** Heavy for quick requests, but worth it.
**Real-life use:** Found a failing POST request because my JSON format was slightly wrong-caught in minutes with Postman.

### 3. VS Code Debugger -Step Through Like a Pro

Console logs are good, but breakpoints are better. [**VS Code’s debugger**](https://code.visualstudio.com/docs/debugtest/debugging) lets you step through code, inspect variables, and skip the log spam.

**Pros:** Works out of the box for most setups.
**Cons:** Needs a little config for Node or SSR React apps.
**Real-life use:** Used it to track a memory leak in a Node app that would have taken hours with just logs.

### 4. Git Bisect-Hunt Down That Buggy Commit

[Git Bisect ](https://git-scm.com/docs/git-bisect)is my secret weapon for finding which commit broke something.

**Pros:** Super quick for regression bugs.
**Cons:** Needs a reproducible test case to work.
**Real-life use:** Once tracked a two-week-old bug to a single commit-without bisect, I would have blamed the wrong code.

### 5. Sentry-Production Bug Tracking

Logs are nice, [but Sentry](https://sentry.io/welcome/?utm_source=chatgpt.com) shows exactly where things break, with stack traces and user context.

**Pros:** Alerts, detailed reports, and user sessions.
**Cons:** Free plan has limits.
**Real-life use:** Found a Safari-only bug through Sentry that users were silently suffering from.

### 6. Wireshark -Deep Network Debugging

When requests just disappear, [Wireshark](https://www.wireshark.org) is my last resort.

**Pros:** Lets you inspect network packets in detail.
**Cons:** Steep learning curve if you’re new.
**Real-life use:** Found a proxy misconfiguration dropping requests randomly -without this, I would still be guessing.

### 7. Docker Logs & Exec-Debug Inside Containers

For containerized apps, `docker logs` and `docker exec` are must-haves.

**Pros:** Lets you debug live containers easily.
**Cons:** Requires Docker know-how.
**Real-life use:** Jumped into a running container to check environment variables -found a missing config in minutes.

### 8. ESLint & Prettier -Prevent Bugs Before They Happen

Clean code = fewer bugs. ESLint catches silly mistakes, and Prettier keeps code consistent.

**Pros:** Prevents small bugs early.
**Cons:** Can feel noisy if rules aren’t set right.
**Real-life use:** ESLint once caught an unused variable that was silently breaking production.

### 9. Log Monitoring Tools (Graylog, Kibana)

When something breaks in production, logs tell the story. Centralized logging saves hours of guesswork.

**Pros:** View logs across services in one place.
**Cons:** Needs setup and server resources.
**Real-life use:** Traced a payment failure flow across microservices in minutes-without touching code.

### 10. Rubber Duck Debugging

Rubber duck debugging is old but gold. Explaining the bug to someone else (or a literal rubber duck) works surprisingly well.

**Pros:** Free, instant clarity.
**Cons:** People may look at you weirdly.
**Real-life use:** Many times, just writing a Slack message describing the bug made the solution pop into my head before I hit send.

Top 10 Debugging Tools Every Developer Should Know

Top 10 Debugging Tools

![](https://cdn-images-1.medium.com/max/1600/1*UT4ba9T-aHcEsD7vy76GhA.png)

Hey I am Jaytech to be honest -when I first started using ChatGPT, most of the answers felt… *meh*. Too generic, too flat, too not what I wanted.

Then I realized the problem was not the tool. It was *me*. Or more specifically-the way I was asking.

Once I started tweaking my prompts, the replies became sharper, more useful and sometimes even fun.

[Non Members](https://medium.com/@jaydipkumarjha/87c12d9fcf16?sk=846eb98cd65139bc92ed07d7360f2a8a)

So here are **five simple tricks** I use now. Nothing technical -just little changes that make a big difference.

### 1. Be Specific, Not Vague

I used to type stuff like:
*Help me write content.*

Guess what I got? A boring, plain reply that looked like homework.

But the moment I got specific-boom, it clicked.

**Example:**
*Write a 100-word Instagram caption about morning routines in a casual, relatable tone.*

Now the reply feels like something I can actually post. The clearer you are, the better ChatGPT gets you.

### 2. Give It a Role

This one changed everything for me. When I ask ChatGPT as if it’s a person with a job, the answers instantly shift.

**Instead of:**
*Give me productivity tips.*

**I will say:**
*Act as a productivity coach. Suggest a 7-day plan to beat procrastination.*

And suddenly, the reply sounds like a coach guiding me step by step -not just a random list. You can assign it any role -marketer, writer, teacher, even a stand-up comedian.

### 3. Share Your Goal

This one is underrated. If ChatGPT does not know my *goal*, the answer does not land right.

**Example:**
*I want to pitch my service to a client-help me write a persuasive 3-line pitch.*

Now it knows the purpose (client pitch) and adjusts the tone. Compare that with just saying, *Write something persuasive.* The first one feels usable, the second feels… off.

### 4. Show the Style You Like

Sometimes the reply is fine, but the *tone* feels off -too robotic, too stiff, or just not me. That’s when I give it an example.

**Example:**
*Write a post like this one \[paste example], but about remote freelancing.*

It’s like saying, Copy this mood. This trick works best for blogs, captions, or anything where voice matters.

### 5. Ask for Steps

When I need something explained, I don’t just type:
*Explain this.*

I go with:
*Break down how to start a YouTube channel into 5 beginner-friendly steps with tools and tips.*

That way, I get clear directions instead of a messy wall of text. Steps = clarity.

### Final Words ❤️

These are not really [hacks.They](https://hacks.They) are just better ways of asking.

1. **Be clear**
2. **Give context**
3. **Show what you want**

That’s it. Once I started doing this, ChatGPT went from giving blah replies to answers I could actually use.

 Top 5 Prompt Tricks That Changed How I Use ChatGPT 🚀

Top ChatGPT Prompts…

It’s 2 a.m. I’m three Red Bulls deep, debugging a layout issue that appeared out of nowhere.

The CSS looks fine. The markup looks fine.

***My soul? Not so much.***

In desperation, I install *one* NPM package. Hit save. Boom. Fixed.

**And that’s when it hit me:** I don’t write JavaScript. I compose symphonies of dependencies.

> **My job? 10% writing code, 90% knowing what package to install.**

Here are the top 10 NPM packages that keep me (relatively) sane.

**Some are old friends. Some are new obsessions. All are absolutely essential.**

> [You can read the full story for free by clicking here](https://medium.com/@fireprogrammer/top-10-npm-packages-i-cant-live-without-e77d3e79e658?sk=43048f7374cc6a85c51a4bd32e0d44a5)

![](https://cdn-images-1.medium.com/max/1600/1*gBQh_aomj2IpCkNYy9R_fQ.png)

### 1. Prettier

> Because code formatting arguments are a waste of life.

Look, I’m not here to debate tabs vs spaces. Prettier doesn’t care, and neither should you.

It formats your code *one way* — the right way. Every time I save, my mess turns into beauty. It’s like auto-tune for code.

```
npm install --save-dev prettier
```

> Use it. Love it. Never look back.

### 2. ESLint

> Because you’re not as perfect as you think you are.

I used to believe I was a clean coder.

**ESLint showed me the truth:** I was writing spaghetti with extra cheese.

From catching unused variables to enforcing best practices, ESLint is like that brutally honest friend who tells you when your code stinks.

Bonus points for pairing it with Prettier.

```
npm install eslint --save-dev
```

### 3. dotenv

> Stop hardcoding secrets, you maniac.

If you’ve ever pushed an API key to GitHub, we need to talk.

`dotenv` lets you store environment variables in a `.env` file like a civilized developer.

```
npm install dotenv
```

Then just:

```
require('dotenv').config();console.log(process.env.MY_SECRET);
```

> Your future self will thank you.

### 4. axios

> Because `fetch` is fine, but axios is divine.

Yeah, yeah, `fetch` is built-in. But have you ever chained error handling with it?

**Axios just *works* better. Cleaner syntax.**

Built-in JSON handling. Interceptors. It’s like fetch, but with manners.

```
npm install axios
```

### 5. nodemon

> Because restarting your server manually is medieval.

Every time I used to `Ctrl + C` and restart the server, a piece of me died.

`nodemon` watches for changes and restarts your app for you. It’s the lazy dev’s best friend.

```
npm install --save-dev nodemon
```

Add it to your scripts and *stop suffering*.

### 6. chalk

> Because your terminal deserves a little flair.

Who said logs have to be boring? `chalk` lets you color your console output, and suddenly [`console.log`](https://console.log) feels like performance art.

Debugging becomes less dreadful when it looks like a rainbow.

```
npm install chalkconsole.log(chalk.green('Success!'));
```

### 7. lodash

> Because JavaScript has weird gaps.

Sure, JS has improved. But `lodash` still fills in the gaps with grace.

**Deep clones? Debounce? Throttle?** Yup.

It’s like carrying a Swiss army knife in your code.

```
npm install lodash
```

Also, `_.get()` alone is worth the price of admission.

### 8. date-fns

> Because [moment.js](https://moment.js) is a heavy dinosaur.

Need to format, parse, or manipulate dates without shipping a time machine worth of bytes?

`date-fns` is modern, modular, and elegant.

```
npm install date-fnsimport { format } from 'date-fns';console.log(format(new Date(), 'yyyy-MM-dd'));
```

### 9. jsonwebtoken

> Because auth is hard, but this helps.

User authentication isn’t optional.

`jsonwebtoken` makes signing and verifying JWTs *almost* painless. Almost.

```
npm install jsonwebtoken
```

> Remember: with great tokens comes great responsibility.

### 10. uuid

> Because IDs should be unique. Duh.

If you’re generating IDs manually, stop. `uuid` is fast, standards-compliant, and idiot-proof.

```
npm install uuidimport { v4 as uuidv4 } from 'uuid';console.log(uuidv4());
```

It’s like giving every object a digital passport.

### Honorable Mentions

* `cors`: **Because you love testing locally and hate errors.**
* `express`: B**ecause Fastify fans will still argue, but Express works just fine.**
* `react-icons`: **Because nobody wants to download SVGs manually anymore.**

### Finally, Use Tools, Not Crutches

> **Let’s be clear. These packages don’t write your code.**

> **They just make the job less of a grind.**

But be warned: NPM addiction is real. Don’t install packages just because you *can*.

Use the ones that make you faster, smarter, and slightly less likely to rage-quit.

> Agree? Disagree? Got a holy-grail package I missed?

> Smash that clap button, drop a comment, or roast me in the replies.

> I’m all ears (and caffeine).

Happy coding!

<h3 id="1-prettier">1. Prettier</h3>
<blockquote>
Because code formatting arguments are a waste of life.
</blockquote>
Look, I’m not here to debate tabs vs spaces. Prettier doesn’t care, and neither should you.
It formats your code one way — the right way. Every time I save, my mess turns into beauty. It’s like auto-tune for code.
<pre><code class="code-highlight">npm install --save-dev prettier
</code></pre>
<blockquote>
Use it. Love it. Never look back.
</blockquote>
<h3 id="2-eslint">2. ESLint</h3>
<blockquote>
Because you’re not as perfect as you think you are.
</blockquote>
I used to believe I was a clean coder.
ESLint showed me the truth: I was writing spaghetti with extra cheese.
From catching unused variables to enforcing best practices, ESLint is like that brutally honest friend who tells you when your code stinks.
Bonus points for pairing it with Prettier.
<pre><code class="code-highlight">npm install eslint --save-dev
</code></pre>
<h3 id="3-dotenv">3. dotenv</h3>
<blockquote>
Stop hardcoding secrets, you maniac.
</blockquote>
If you’ve ever pushed an API key to GitHub, we need to talk.
<code>dotenv</code> lets you store environment variables in a <code>.env</code> file like a civilized developer.
<pre><code class="code-highlight">npm install dotenv
</code></pre>
Then just:
<pre><code class="code-highlight">require('dotenv').config();console.log(process.env.MY_SECRET);
</code></pre>
<blockquote>
Your future self will thank you.
</blockquote>
<h3 id="4-axios">4. axios</h3>
<blockquote>
Because <code>fetch</code> is fine, but axios is divine.
</blockquote>
Yeah, yeah, <code>fetch</code> is built-in. But have you ever chained error handling with it?
Axios just works better. Cleaner syntax.
Built-in JSON handling. Interceptors. It’s like fetch, but with manners.
<pre><code class="code-highlight">npm install axios
</code></pre>
<h3 id="5-nodemon">5. nodemon</h3>
<blockquote>
Because restarting your server manually is medieval.
</blockquote>
Every time I used to <code>Ctrl + C</code> and restart the server, a piece of me died.
<code>nodemon</code> watches for changes and restarts your app for you. It’s the lazy dev’s best friend.
<pre><code class="code-highlight">npm install --save-dev nodemon
</code></pre>
Add it to your scripts and stop suffering.
<h3 id="6-chalk">6. chalk</h3>
<blockquote>
Because your terminal deserves a little flair.
</blockquote>
Who said logs have to be boring? <code>chalk</code> lets you color your console output, and suddenly <a href="https://console.log"><code>console.log</code></a> feels like performance art.
Debugging becomes less dreadful when it looks like a rainbow.
<pre><code class="code-highlight">npm install chalkconsole.log(chalk.green('Success!'));
</code></pre>
<h3 id="7-lodash">7. lodash</h3>
<blockquote>
Because JavaScript has weird gaps.
</blockquote>
Sure, JS has improved. But <code>lodash</code> still fills in the gaps with grace.
Deep clones? Debounce? Throttle? Yup.
It’s like carrying a Swiss army knife in your code.
<pre><code class="code-highlight">npm install lodash
</code></pre>
Also, <code>_.get()</code> alone is worth the price of admission.
<h3 id="8-date-fns">8. date-fns</h3>
<blockquote>
Because <a href="https://moment.js">moment.js</a> is a heavy dinosaur.
</blockquote>
Need to format, parse, or manipulate dates without shipping a time machine worth of bytes?
<code>date-fns</code> is modern, modular, and elegant.
<pre><code class="code-highlight">npm install date-fnsimport { format } from 'date-fns';console.log(format(new Date(), 'yyyy-MM-dd'));
</code></pre>
<h3 id="9-jsonwebtoken">9. jsonwebtoken</h3>
<blockquote>
Because auth is hard, but this helps.
</blockquote>
User authentication isn’t optional.
<code>jsonwebtoken</code> makes signing and verifying JWTs almost painless. Almost.
<pre><code class="code-highlight">npm install jsonwebtoken
</code></pre>
<blockquote>
Remember: with great tokens comes great responsibility.
</blockquote>
<h3 id="10-uuid">10. uuid</h3>
<blockquote>
Because IDs should be unique. Duh.
</blockquote>
If you’re generating IDs manually, stop. <code>uuid</code> is fast, standards-compliant, and idiot-proof.
<pre><code class="code-highlight">npm install uuidimport { v4 as uuidv4 } from 'uuid';console.log(uuidv4());
</code></pre>
It’s like giving every object a digital passport.
<h3 id="honorable-mentions">Honorable Mentions</h3>
<ul>
<li><code>cors</code>: Because you love testing locally and hate errors.</li>
<li><code>express</code>: Because Fastify fans will still argue, but Express works just fine.</li>
<li><code>react-icons</code>: Because nobody wants to download SVGs manually anymore.</li>
</ul>
<h3 id="finally-use-tools-notcrutches">Finally, Use Tools, Not Crutches</h3>
<blockquote>
Let’s be clear. These packages don’t write your code.
</blockquote>
<blockquote>
They just make the job less of a grind.
</blockquote>
But be warned: NPM addiction is real. Don’t install packages just because you can.
Use the ones that make you faster, smarter, and slightly less likely to rage-quit.
<blockquote>
Agree? Disagree? Got a holy-grail package I missed?
</blockquote>
<blockquote>
Smash that clap button, drop a comment, or roast me in the replies.
</blockquote>
<blockquote>
I’m all ears (and caffeine).
</blockquote>
Happy coding!

Top 10 NPM Packages I Can’t Live Without

Preparing for a JavaScript interview can be intimidating, but mastering common coding challenges can boost your confidence and help you stand out. This article dives into **11 essential JavaScript problems**, offering solutions and explanations to sharpen your problem-solving skills. These challenges test concepts like strings, arrays, loops, and logic — all crucial topics for technical interviews.

![](https://cdn-images-1.medium.com/max/1600/1*we7fVDneFjHIDU1kL_YNlA.jpeg)

### 1. Reverse a String

Reversing a string is a common challenge that demonstrates your understanding of strings and JavaScript’s built-in methods.

```
function reverse(str) { return str.split('').reverse().join('');}let input = "demha";let output = reverse(input);console.log(`The Reverse of ${input} is ${output}`); // Output: "ahmed"
```

**Explanation:**

* `split('')` converts the string into an array of characters.
* `reverse()` reverses the array.
* `join('')` converts the array back into a string.

### 2. Palindrome Test

A palindrome is a word that reads the same forwards and backwards.

```
function palindrome(str1, str2) { let reversed = str1.split('').reverse().join(''); return reversed.toLowerCase() === str2.toLowerCase();}const str1 = "Ahmed";const str2 = "demha";console.log(palindrome(str1, str2)); // Output: true
```

**Explanation:**

* Reverse the first string.
* Compare it (case-insensitive) to the second string.

### 3. Most Frequent Character

Identify the character that appears most frequently in a string.

```
function mostFrequentChar(str) { const charCount = {}; let maxChar = '', maxCount = 0; for (let char of str) { charCount[char] = (charCount[char] || 0) + 1; if (charCount[char] > maxCount) { maxChar = char; maxCount = charCount[char]; } } return maxChar;}const input = "ABBAAdBd5BBB";console.log(mostFrequentChar(input)); // Output: 'B'
```

**Explanation:**

* Use an object to count character occurrences.
* Track the character with the maximum frequency.

### 4. Chunk an Array

Divide an array into smaller chunks of a specified size.

```
function chunk(array, size) { const output = []; for (let i = 0; i < array.length; i += size) { output.push(array.slice(i, i + size)); } return output;}let array = [1, 2, 3, 4, 5, 6, 7];console.log(chunk(array, 3));/* Output:[[1, 2, 3], [4, 5, 6], [7]] */
```

**Explanation:**

* Use a `for` loop to slice the array into smaller parts of `size`.

### 5. Capitalize the First Character of Each Word

This problem tests string manipulation and array methods.

```
function capitalize(sentence) { return sentence.split(' ').map(word => word[0].toUpperCase() + word.slice(1)).join(' ');}let input = "the moon is so beautiful";console.log(capitalize(input)); // Output: "The Moon Is So Beautiful"
```

**Explanation:**

* Split the sentence into words.
* Capitalize the first letter and concatenate the rest.
* Join the words back into a string.

### 6. Anagram Test

Check if two words are anagrams of each other.

```
function cleanText(str) { return str.toLowerCase().replace(/\W/g, '').split('').sort().join('');}function anagrams(str1, str2) { return cleanText(str1) === cleanText(str2);}console.log(anagrams("RAIL! SAFETY!", "fairy tales")); // Output: true
```

**Explanation:**

* Remove non-alphabet characters.
* Sort and compare both strings.

### 7. Count Vowels

Count the number of vowels in a string.

```
function vowelCheck(str) { const vowels = ['a', 'e', 'i', 'o', 'u']; return str.split('').filter(char => vowels.includes(char.toLowerCase())).length;}console.log(vowelCheck("Apple")); // Output: 2
```

**Explanation:**

* Use a filter to identify vowels and count them.

### 8. FizzBuzz

Classic challenge to print numbers and specific words based on divisibility.

```
function fizzBuzz(n) { for (let i = 1; i <= n; i++) { if (i % 3 === 0 && i % 5 === 0) console.log("FizzBuzz"); else if (i % 3 === 0) console.log("Fizz"); else if (i % 5 === 0) console.log("Buzz"); else console.log(i); }}fizzBuzz(15);
```

### 9. Print Steps of (#)

Print steps of increasing `#` for a given size.

```
function steps(n) { for (let i = 1; i <= n; i++) { console.log('#'.repeat(i)); }}steps(3);/* Output:###### */
```

### 10. Print a Pyramid of (#)

Create a pyramid pattern using `#`.

```
function printPyramid(height) { for (let row = 1; row <= height; row++) { let spaces = ' '.repeat(height - row); let hashes = '#'.repeat(2 * row - 1); console.log(spaces + hashes + spaces); }}printPyramid(3);
```

### 11. Spiral Matrix

Generate a square matrix in a spiral order.

```
function spiralMatrix(n) { let matrix = Array.from({ length: n }, () => Array(n).fill(0)); let num = 1, rowStart = 0, rowEnd = n - 1, colStart = 0, colEnd = n - 1; while (rowStart <= rowEnd && colStart <= colEnd) { for (let i = colStart; i <= colEnd; i++) matrix[rowStart][i] = num++; rowStart++; for (let i = rowStart; i <= rowEnd; i++) matrix[i][colEnd] = num++; colEnd--; for (let i = colEnd; i >= colStart; i--) matrix[rowEnd][i] = num++; rowEnd--; for (let i = rowEnd; i >= rowStart; i--) matrix[i][colStart] = num++; colStart++; } return matrix;}console.log(spiralMatrix(3));
```

### Final Thoughts

By solving these 11 JavaScript challenges, you’ll strengthen your understanding of key concepts and build confidence for your next interview. Focus on writing clean, efficient code and practice explaining your solutions out loud. Good luck!

Top 11 JavaScript Coding Challenges to Ace Your Next Interview

![](https://cdn-images-1.medium.com/max/1600/0*8YAmy3EMd9hR3xXq)

Photo by [Artturi Jalli](https://unsplash.com/@artturijalli?utm_source=medium\&utm_medium=referral) on [Unsplash](https://unsplash.com?utm_source=medium\&utm_medium=referral)

It started the night I had three scripts running side-by-side, each trying to solve a problem I didn’t want to touch manually. One script scraped a client’s inventory, another cleaned the data, and the last one generated a PDF report while I made coffee. I realized then, coding like the top 1% isn’t about knowing “more” Python. It’s about knowing the right tools that turn hours of work into seconds of automation.

And here’s the truth: most Python developers never touch these libraries, which is why they stay in the 99%. You’re about to change that.

### 1. Pendulum-lite Alternative

Arrow is the fast, intuitive datetime library you didn’t know you needed. It removes the boilerplate that comes with Python’s `datetime`.

```
import arrowprint(arrow.now().shift(days=+3).format('YYYY-MM-DD'))
```

Perfect for automation scripts that schedule tasks, generate logs, or handle timezone conversions.

### 2. Faker

Why waste time typing fake names and emails? Faker generates them in milliseconds.

```
from faker import Fakerfake = Faker()print(fake.name(), fake.email())
```

It’s a lifesaver when automating tests or mocking datasets.

### 3. TQDM

Automations often run in the background, but sometimes you need visibility. TQDM wraps any iterable with a progress bar.

```
from tqdm import tqdmimport timefor _ in tqdm(range(100)):    time.sleep(0.01)
```

When running big automation jobs, this keeps you from wondering, “Is this still running?”

### 4. YAML

YAML lets you store automation settings in a cleaner, human-readable way.

```
import yamlconfig = yaml.safe_load(open('config.yml'))print(config['api_key'])
```

Instead of hardcoding credentials, you keep them in a `.yml` file and load them dynamically.

### 5. Boto3

From uploading files to S3 to spinning up EC2 instances, Boto3 makes AWS scripting painless.

```
import boto3s3 = boto3.client('s3')s3.upload_file('report.pdf', 'my-bucket', 'report.pdf')
```

You can build full cloud automation workflows without touching the AWS console.

### 6. Airflow

Airflow isn’t just for big companies. It schedules and manages complex automation pipelines.

```
pip install apache-airflow
```

Imagine chaining scripts so they run in perfect order. Airflow does exactly that.

### 7. PyPDF2

Whether it’s merging multiple PDFs or extracting text, PyPDF2 lets you automate the process in seconds.

```
from PyPDF2 import PdfMergermerger = PdfMerger()merger.append('file1.pdf')merger.append('file2.pdf')merger.write('combined.pdf')merger.close()
```

No more dragging files into random online PDF tools.

### 8. FastF1

For automation in niche fields, FastF1 is a Formula 1 data API wrapper. It’s perfect for sports dashboards and analytics.

```
import fastf1fastf1.Cache.enable_cache('cache')session = fastf1.get_session(2023, 'Monaco', 'Q')session.load()print(session.results)
```

Shows how automation isn’t limited to “business” work, it can be for fun too.

### 9. Watchfiles

Think `watchdog`, but faster. Watchfiles runs functions automatically when files change.

```
from watchfiles import watchfor changes in watch('./data'):    print(changes)
```

Great for instant triggers when a file is updated, downloaded, or replaced.

### Closing Words:

Don’t just “collect” libraries, master them. The difference between a good Python developer and a top 1% developer is not knowing what exists, but knowing exactly when to use it.

It’s a lifesaver when automating tests or mocking datasets.
<h3 id="3-tqdm">3. TQDM</h3>
Automations often run in the background, but sometimes you need visibility. TQDM wraps any iterable with a progress bar.
<pre><code class="code-highlight">from tqdm import tqdmimport timefor _ in tqdm(range(100)): time.sleep(0.01)
</code></pre>
When running big automation jobs, this keeps you from wondering, “Is this still running?”
<h3 id="4-yaml">4. YAML</h3>
YAML lets you store automation settings in a cleaner, human-readable way.
<pre><code class="code-highlight">import yamlconfig = yaml.safe_load(open('config.yml'))print(config['api_key'])
</code></pre>
Instead of hardcoding credentials, you keep them in a <code>.yml</code> file and load them dynamically.
<h3 id="5-boto3">5. Boto3</h3>
From uploading files to S3 to spinning up EC2 instances, Boto3 makes AWS scripting painless.
<pre><code class="code-highlight">import boto3s3 = boto3.client('s3')s3.upload_file('report.pdf', 'my-bucket', 'report.pdf')
</code></pre>
You can build full cloud automation workflows without touching the AWS console.
<h3 id="6-airflow">6. Airflow</h3>
Airflow isn’t just for big companies. It schedules and manages complex automation pipelines.
<pre><code class="code-highlight">pip install apache-airflow
</code></pre>
Imagine chaining scripts so they run in perfect order. Airflow does exactly that.
<h3 id="7-pypdf2">7. PyPDF2</h3>
Whether it’s merging multiple PDFs or extracting text, PyPDF2 lets you automate the process in seconds.
<pre><code class="code-highlight">from PyPDF2 import PdfMergermerger = PdfMerger()merger.append('file1.pdf')merger.append('file2.pdf')merger.write('combined.pdf')merger.close()
</code></pre>
No more dragging files into random online PDF tools.
<h3 id="8-fastf1">8. FastF1</h3>
For automation in niche fields, FastF1 is a Formula 1 data API wrapper. It’s perfect for sports dashboards and analytics.
<pre><code class="code-highlight">import fastf1fastf1.Cache.enable_cache('cache')session = fastf1.get_session(2023, 'Monaco', 'Q')session.load()print(session.results)
</code></pre>
Shows how automation isn’t limited to “business” work, it can be for fun too.
<h3 id="9-watchfiles">9. Watchfiles</h3>
Think <code>watchdog</code>, but faster. Watchfiles runs functions automatically when files change.
<pre><code class="code-highlight">from watchfiles import watchfor changes in watch('./data'): print(changes)
</code></pre>
Great for instant triggers when a file is updated, downloaded, or replaced.
<h3 id="closing-words">Closing Words:</h3>
Don’t just “collect” libraries, master them. The difference between a good Python developer and a top 1% developer is not knowing what exists, but knowing exactly when to use it.
