When Platforms Like LinkedIn Fail Developers, We Build Without Them

Rvn — Fri, 04 Jul 2025 07:45:35 +0000

Some of us joined platforms like LinkedIn just to show who we are.

We didn’t spam. We didn’t scam. We didn’t cheat.

We simply signed up, filled in real information, and tried to connect.

And still, we got banned.

🔒 The System Doesn't Want You — Unless You Already "Belong"

Let’s be honest.

LinkedIn claims to be a professional platform for all. But its systems treat newcomers — especially students, early-career devs, or people from underrepresented regions — as if they’re a threat.

Accounts get flagged.

Profiles get banned.

Support stays silent.

And users are blamed for the very actions they’re prevented from controlling.

You get locked out.

Then you're told you have too many accounts.

But you can't log in to delete them.

And they call it “your fault.”

🧱 This Isn’t About One Person. It’s About All of Us.

We’ve seen it. Lived it. Felt it.

Not just one person, or one profile — but a wave of developers shut out for being new, different, or simply visible in the wrong way.

No warnings.

No clear rules.

Just an algorithm that acts like a gatekeeper for a system already broken.

And the worst part?

They don't care.

They don’t listen.

They don’t respond.

They don’t learn.

🔥 But We Do.

We’re the ones writing open-source tools.

We’re the ones building projects late at night, with no company name behind us.

We’re the ones solving problems no one asked us to solve — yet.

And we’re done waiting for permission.

🧠 We Don’t Need Platforms That Shut Us Down to Grow.

If LinkedIn wants to filter us out, silence us, bury us in a pile of auto-generated restrictions and fake professionalism — that’s fine.

We’ll build somewhere else.

Because a platform that fears authenticity doesn’t deserve real builders.

🛠️ They May Not Know Who We Are.

But We Do.

We are the new wave.

We don’t come from prestige, but from practice.

We don’t speak with titles, but with tools.

And we don’t need validation to keep creating.

They built walls.

We’ll build bridges.

They closed doors.

We’ll make our own platforms.

This is our voice.

And no algorithm can silence that.

– a voice among many.

✊ If You’ve Been Through the Same…

Comment below.

Tell your story.

Let’s show the world that we’re more than broken profiles and restricted accounts.

We are developers.

We build.

We learn.

We adapt.

And no algorithm will stop that.

🔐 Secure Auth Token Handling in the Frontend: When Your Client Needs the Token

Rvn — Sat, 21 Jun 2025 15:27:38 +0000

💬 “Do you have any tips for auth flows where the client legitimately needs the token for APIs?”
This is one of the most common — and dangerous — pain points for modern web devs.

If you’ve ever built a frontend app that needs to call an API, you’ve probably asked:

👉 Where do I store the token safely?
👉 How do I protect against XSS or CSRF?
👉 What if the client actually needs the token to work?

Let's walk through why this is tricky, and how to design a secure flow that balances usability and security — even when the client needs access to the token.

🧠 Why It’s Dangerous: The Frontend is an Unsafe Place

Your browser app (React, Vue, Svelte, etc.) runs in a sandboxed environment… but it’s still exposed to the DOM, scripts, and user extensions. That makes it vulnerable to:

🧨 XSS (Cross-Site Scripting): Malicious scripts can steal tokens if they’re stored in localStorage or sessionStorage.
🪝 CSRF (Cross-Site Request Forgery): If you're using cookies incorrectly, attackers can trick users into making unwanted requests.

So yes, you should be very careful when storing or exposing tokens on the frontend. But sometimes — you have to.

✅ Legit Use Cases Where Client Needs the Token

There are valid reasons why your frontend app may need direct access to a token:

Calling 3rd-party APIs (e.g., Stripe, Firebase, or custom backend services)
Using GraphQL clients like Apollo that inject tokens into headers
Managing mobile apps or Electron apps that mimic frontend environments
Single-page apps (SPAs) where API access is deeply integrated into UI logic

So, let’s build a secure plan.

🧰 5 Secure Practices for Token-Based Auth on the Frontend

1. 🛑 Avoid `localStorage` for Sensitive Tokens

It's easy. It's tempting. But it's not safe.

// ❌ Not secure
localStorage.setItem("token", yourJWT);

Why not? Because if any script on your site is compromised — even via a small XSS vulnerability — your token is instantly leaked.

Use localStorage only if:

It’s a public-access token
The token has limited access scope
You’ve fully audited your code for XSS protection

Otherwise...

2. ✅ Use In-Memory Storage for Access Tokens

Store the token in memory (e.g., in a React context or state variable). This way, it's never written to disk and disappears when the page is refreshed.

// ✅ Safer: only in memory
let accessToken = null;

function login() {
  accessToken = fetchToken();
}

function callAPI() {
  fetch("/api/data", {
    headers: {
      Authorization: `Bearer ${accessToken}`,
    },
  });
}

Pros:

Not vulnerable to XSS
Not persistent after refresh (good for security)

Cons:

You lose the token on refresh. This is where a refresh token helps.

3. 🔁 Use HttpOnly Cookies for Refresh Tokens

Refresh tokens are designed to get new access tokens silently. Store the refresh token in an HttpOnly, Secure, SameSite=Strict cookie.

Set-Cookie: refresh_token=abc.def.ghi; HttpOnly; Secure; SameSite=Strict

HttpOnly = JS can’t touch it ✅
Secure = Only sent over HTTPS ✅
SameSite = Prevents CSRF ✅

When the access token expires, the client can request a new one via an API route that automatically uses the refresh token.

4. 📦 Use a Secure Auth Pattern: "Split Token Storage"

Here’s a hybrid approach many modern apps use:

Token Type	Where to Store	Lifetime	Usage
Access Token	Memory only	Short (5–15 min)	Sent in headers, manually
Refresh Token	HttpOnly Cookie	Long (7–30 days)	Used by backend to re-issue

This pattern ensures:

⚔️ No tokens are exposed in JavaScript
🔁 Session can be refreshed silently
🔐 Access token is never stored on disk

5. 🛡️ Add Extra Layers of Protection

Don’t stop at token handling. Secure your entire stack:

CSP (Content Security Policy): Prevent inline scripts
XSS Protection: Sanitize all inputs & templates
Token Rotation: Invalidate and replace old tokens regularly
Audit Headers: Set X-Content-Type-Options, X-Frame-Options, etc.
Scopes & Claims: Use role-based access with JWT claims to limit token power

🧪 Real-World Flow Example (React + Express)

Here’s a simplified version:

Login Flow:

User logs in via /api/login
Backend:

Sends access token → response JSON (short-lived)
Sends refresh token → HttpOnly cookie (long-lived)
1. Frontend:
Stores access token in memory

Accessing API:

React app sends Authorization: Bearer <access_token> in headers

Token Expired?

API returns 401
Frontend silently requests /api/refresh (uses HttpOnly refresh cookie)
Backend sends a new access token
App retries the original request

🧠 TL;DR – Best Practices

❌ Don’t store sensitive tokens in localStorage
✅ Keep access tokens in memory only
🍪 Use HttpOnly cookies for refresh tokens
♻️ Rotate and expire tokens properly
🧱 Harden your frontend with CSP and XSS protections

💬 Final Thoughts

Yes — sometimes the client needs the token. But with the right architecture, you can still stay safe, fast, and scalable.

If you’re building an SPA or mobile frontend, designing a robust auth system is one of the most valuable skills you can develop as a dev.

🛠️ 1 Tool That Feels Like Cheating (but Isn’t) – Meet `tldraw`

Rvn — Sat, 21 Jun 2025 15:17:37 +0000

✨ A tool so smooth, it feels like magic.
🎨 A whiteboard, a design surface, a collaboration space — all in one.

😳 “This feels like cheating...”

As a developer or indie maker, how many times have you opened up Figma, Miro, or a basic drawing tool just to sketch out an idea — and immediately felt friction?

Too many buttons.
Too many steps.
Too slow to just... think visually.

That’s where tldraw changes everything.

🚀 What is `tldraw`?

tldraw is a free, open-source whiteboard tool designed for instant thinking.
But don’t let the word “whiteboard” fool you — it’s so much more.

✅ What makes it special:

Instant use. Open the site — no sign-up needed.
Real-time multiplayer. Invite a friend — you both draw live.
Drag-and-drop UI design. Sketch apps, flows, and systems.
Markdown, shapes, stickies, connectors. Perfect for dev planning.
Open source. Self-host it or build on top.

👨‍💻 How Developers Use It

Here’s how I (and many other devs) use tldraw every day:

🧠 1. Thinking Through Features

Before writing code, I’ll sketch out logic or page layouts.
Not pretty — just fast. I can drag arrows between parts and write notes inline.

"It's like drawing on glass with my brain plugged in."

🧪 2. Explaining Systems to Others

When a client or team asks, "How does this API flow work?"
Boom — open tldraw, diagram it in real time, and everyone gets it.

🛠️ 3. Designing Without Getting Stuck

I don’t want Figma layers or design tokens. I just want to explore.
tldraw helps me stay in build mode without switching to pixel-perfect mode.

🔥 Bonus Power: Self-Hosting

Want to use tldraw for your startup? You can fork it on GitHub and:

Integrate it into your product
Add custom elements
Save/load diagrams in your app
Use it as a collaborative playground

GitHub repo → https://github.com/tldraw/tldraw

😌 Why It Feels Like Cheating

It’s not just fast — it’s freeing.
You go from idea → diagram → shared understanding in seconds.

You don’t need to think about the tool.
You just think — and the tool follows.

🧠 Final Thought

Good tools disappear.
Great tools feel like superpowers.

tldraw is one of those. Try it once — and you'll start using it every day.

🧠 You're Trusting `localStorage`… You Shouldn’t 😬

Rvn — Fri, 20 Jun 2025 09:15:00 +0000

We’ve all done it.
Quick login logic. JWT or token in hand.
localStorage.setItem("token", yourToken) — boom, done. Feels safe. Feels clean. Feels… modern.

But here’s the hard truth:

Anything in localStorage is accessible to any script on the page — malicious or not.

This isn’t a nitpick. This is a real attack vector you may have just handed over to a rogue third-party script, a careless plugin, or even a compromised CDN. Let's break this down.

🚨 The False Sense of Security

localStorage is often mistaken for a secure place to keep sensitive data like:

JWT access tokens
User credentials
Refresh tokens
Session states

It’s fast, persistent, and easy to use — but it’s also entirely exposed to the browser’s JavaScript environment. That means:

console.log(localStorage.getItem("token")) 
// returns your secret like candy from a vending machine

Now imagine this line existing inside a third-party script you included — maybe an analytics tool, a chat widget, or a library you forgot to audit.
If it can run, it can read.

🧠 Let’s Visualize It

Let’s say your login flow stores a JWT:

localStorage.setItem("accessToken", jwt);

Now let’s say a malicious script runs on the same domain:

const stolen = localStorage.getItem("accessToken");
sendToHacker(stolen);

That’s it. No hacking tools needed.
Just the same access your app has — but used against you.

🔐 The Safer Alternative: `httpOnly` Secure Cookies

If you're storing sensitive auth tokens on the client, the right move is often to:

✅ Store them in cookies
✅ Mark them as httpOnly
✅ Mark them as secure and SameSite=Strict when appropriate

Here’s why this works:

Method	Can JS Access It?	Sent Automatically with Requests?	Ideal For
`localStorage`	✅ Yes	❌ No	Non-sensitive app state
`httpOnly` Cookie	❌ No	✅ Yes	Auth/session tokens

A typical Express.js or backend setup would look like this:

res.cookie("accessToken", token, {
  httpOnly: true,
  secure: true,
  sameSite: "Strict", // or "Lax" depending on your use case
});

Now that cookie is:

Sent only to your server
Inaccessible from JavaScript
Protected from XSS-based token theft

🤯 Common Objection: “But I Need It in JS!”

Sometimes devs say:

"I use my token in frontend API calls, so I need to read it in JavaScript."

But if you must access your token in the client, at least:

Never persist it beyond the session (sessionStorage > localStorage)
Consider encrypted IndexedDB + user-specific key
Store minimal privilege tokens client-side
Protect the token lifecycle with refresh tokens that are httpOnly

Still, the ideal solution for most use cases is to design your API and frontend so that auth happens via httpOnly cookies, with CSRF protection in place.

💡 Bonus Tip: Use Subresource Integrity (SRI)

If you include third-party scripts from CDNs, always use Subresource Integrity (SRI) hashes:

<script src="https://cdn.example.com/library.js"
        integrity="sha384-abc123..."
        crossorigin="anonymous"></script>

This ensures the script hasn’t been tampered with.

✅ TL;DR — Fix the Front Too

🔓 localStorage is like a safe with no lock — anyone with JavaScript access can peek in.

Instead:

🛡 Store sensitive data in httpOnly cookies
🔒 Use secure and SameSite flags
🚫 Keep tokens out of the JS runtime if possible
🎯 Be intentional with what your frontend really needs to know

🎬 Watch It as a Short (Cinematic Edition)

⚡ Make Your App Feel Instant with One Line: `requestIdleCallback()

Rvn — Thu, 19 Jun 2025 09:19:42 +0000

Ever feel like your app should be fast…
But somehow still feels heavy?

Sometimes, the slowdown isn’t about what you're doing —
It’s when you're doing it.

Let’s fix that with a tiny but powerful native tool:

🧠 What Is `requestIdleCallback()`?

requestIdleCallback() lets the browser delay a task until the main thread is free.
That means it only runs when the user isn’t actively interacting — like between frames, or during idle time.

Translation?
Less jank. Happier users. Faster feel.

❌ The Problem: Too Much Work During Render

Imagine you’re doing this:

cleanupDOM();
trackAnalytics();
recalculatePositions();

If this happens immediately after user interaction, the browser is forced to do everything now, which can delay animations, clicks, or even typing.

✅ The Fix: Let the Browser Decide

requestIdleCallback(() => {
  cleanupDOM();
});

Now that non-urgent cleanup happens only when it won’t block the UI.

✨ Bonus: It’s Natively Supported (and Polyfillable)

It works in modern browsers, and for older ones, you can polyfill with:

window.requestIdleCallback =
  window.requestIdleCallback ||
  function (handler) {
    return setTimeout(() => handler({ timeRemaining: () => 0 }), 1);
  };

🎯 Real Example

Before:

onUserAction(() => {
  updateUI();
  clearOldDOMNodes(); // slow!
});

After:

onUserAction(() => {
  updateUI();
  requestIdleCallback(() => clearOldDOMNodes());
});

Result:

Faster initial reaction
Less layout shift
Happier dev AND user ✨

🔍 When to Use It

✅ For non-critical UI cleanup
✅ For off-screen DOM removal
✅ For logging, tracking, deferred loading
✅ Anytime your code can wait a little

🛑 Don’t use it for things the user is expecting right now, like validation or transitions.

🧠 Why It Feels So Good

Sometimes the tiniest changes give the biggest satisfaction.
This one-liner gives your app the illusion of instant speed, without a full rewrite or new library.

It’s not cheating.
It’s smart dev timing.

🛠️ TL;DR

requestIdleCallback(() => {
  // run non-blocking, non-urgent code here
});

✅ Boosts perceived speed
✅ Super lightweight
✅ Native and modern
✅ Satisfying to use 😌

💬 Your Turn

Ever used requestIdleCallback() in production?
Or have a favorite micro-performance trick of your own?

🧠 You Fixed the Bug… So Why Do You Feel Nothing?

Rvn — Wed, 18 Jun 2025 08:40:47 +0000

“✅ Build successful.”
And yet…
You just stare. No smile. No joy.
Just... emptiness.

🐞 The Bug Was Brutal

You spent 3 hours chasing a shadow.
Nested callbacks, forgotten state, invisible mutation… maybe all of it.

You went deep:

Stepped through debugger like a surgeon
Added and removed a hundred console.logs
Rewrote part of the logic tree
Gave up twice
Came back once more — and found it

And then…
It worked.
But you didn’t cheer.

🥀 Why Devs Feel Nothing After Wins

You’re not alone. Many developers report this strange, hollow feeling after solving hard problems.

A few real reasons why:

🧠 Mental fatigue. You burned your fuel getting here.
🕳️ No feedback loop. No one saw how deep the rabbit hole went.
🎯 Next-ticket syndrome. You’re already thinking about what’s next.
😞 Inner critic. You blame yourself for not solving it faster.

We don’t celebrate because we’re conditioned to move forward — not pause.

💡 Tiny Wins Deserve Big Respect

Fixing a bug is not just fixing code.
It’s:

Clarifying chaos
Untangling logic
Communicating with your past self (and future bugs)
Recovering a broken part of something you care about

That’s not “just fixing.”
That’s healing.

🌱 Action: Make Space to Feel Proud

Here’s what helps — really:

✅ 1. Take 60 seconds to reflect

Literally just pause and think:

“That was tricky. I stuck with it. I didn’t quit.”

It rewires your brain to recognize effort.

✅ 2. Write it down (just for you)

Create a “Bug Graveyard” file or journal.
Every time you fix something painful, log it like:

### 🐛 2025-06-13 — Broken Auth Redirect
Took 2 hours.  
Problem: wrong env var in Next.js edge middleware  
Fix: moved logic to server + added fallback  
Lesson: always test redirects from production flow

These become powerful proofs of progress.

✅ 3. Share quietly — or loudly

Post it in your dev Slack.
Tweet: “Spent 4 hours on a dumb bug. Fixed it. I am invincible.”
Or just say to yourself: “Good job, me.”

❤️ Final Thought

Not every victory comes with applause.
But every victory matters.

Next time you fix something hard — and you don’t feel anything — remember this:

🎯 You did it.
🎯 You mattered in that moment.
🎯 Be proud. Even if it's just you who knows.

💬 Let’s Normalize Silent Wins.
Ever felt this before?
Drop your story in the comments — someone else probably needs to hear it.

🧠 You Fixed It… and No One Saw 😶

Rvn — Tue, 17 Jun 2025 04:40:18 +0000

Debugging is one of the hardest — and most invisible — skills in tech.

🐞 The Bug No One Could Solve…

There’s a special kind of silence in dev life:

The logs are messy.
The bug is buried layers deep.
Everyone tried — and gave up.

But then you sit down.
No big speeches. No help. Just you, the console, and your mind in deep focus mode.

You trace it. Test it. Hunt it. Break it.
And finally… fix it.
No big reaction. Just one clean test pass ✅

No one saw the chaos.
No one will ever know what it took.

And yet… you know.
And that’s enough.

🔍 What Debugging Really Looks Like

Debugging isn’t glamorous — but it’s the real heart of software development.

It’s not about adding features. It’s not shipping new pages.
It’s about solving a system that no longer plays by the rules.

Real examples:

🔄 A memory leak caused by a closure inside a setInterval — took 4 hours to find
🧵 Race conditions inside async queue logic — passed tests but failed randomly *⚠️ Production crash caused by a hidden circular import — only in serverless builds
🐛 A styling bug that only happened in Safari 15.1 (yes, that specific)

These aren’t stories people tell on stage.
They’re the ghost fights — invisible wins that keep the system running.

👁️ Debugging = Invisible Mastery

Most people think debugging is just “fixing what’s broken.”
But real debugging means:

Understanding code you didn’t write
Recognizing symptoms and tracing back to root cause
Reading logs like they’re mystery novels
Knowing when to console.log, and when to pause and think

It’s problem-solving at a deep level.
Not flashy. But real.

💬 No One Applauds Debuggers

When you add a feature, the UI changes.
When you deploy a fix… everything looks the same.

And yet:

The app is stable
The team moves faster
The customer never sees the crash

Debuggers are the silent protectors of every codebase.

🤝 For the Devs in the Shadows

If you’ve ever:

Solved a bug that no one could reproduce
Cleaned up code that was never documented
Fixed something you couldn’t even explain in words…

This post is for you.

You won’t get applause.
You won’t trend.
But you’ll sleep better — because you know what you did.

🧘 Final Thought

Writing code is exciting.
But fixing code — that’s wisdom.

So next time you solve a bug and no one sees it?

Pause.
Take a breath.
And remind yourself:

That’s dev life.
Silent wins. Quiet mastery. 🧠

🧠 You Showed Up… Even With Nothing Left

Rvn — Mon, 16 Jun 2025 07:33:45 +0000

✨ “That’s not weakness.
That’s discipline. That’s you.”

You didn’t want to open the editor today.
Your brain said “rest.”
Your body said “quit.”
But your instinct whispered:

“Just one more line. Just one more try.”

And somehow…
You showed up.

🧱 Dev Grit: What They Don’t Teach You

You can learn all the syntax in the world,
Master every framework,
Write perfect functions.

But nobody teaches you this:
Some days, the real challenge is opening the IDE.

⚠️ Signs You’re There Right Now:

You reread the same line 5 times, nothing sticks
You feel “guilty” for resting, but too drained to code
You’re doing 2 hours of work in 6
You push one small commit — and it feels like a marathon

Sound familiar?

You’re not lazy. You’re mentally exhausted.
And yet... you’re still here. That matters.

💡 The Science: Willpower, Dopamine, and Burnout

🔬 Studies show that cognitive fatigue doesn’t always mean your brain is out of power — it means your reward system is out of fuel.

You're pushing through without dopamine.
Without the "why."
Without applause.

That's not weakness.
That's internal discipline.
That's you showing up even when it’s invisible.

🎯 One Commit = 100% Today

“Just one commit”
“Just fix the spacing”
“Just finish the test case”

These tiny actions might look like nothing.
But they’re actually mental resistance reps — the kind that make you anti-fragile.

🧠 What To Do When You Feel Like This

1. Set a “low bar” win

Give yourself permission to do less:

One bug fix
Refactor one line
Rename one variable

Small progress > no progress.

2. Honor the energy cost

After you commit:

🎉 Celebrate
💧 Rest
💤 Walk away

You don’t need to “make up for lost time.”
You earned the pause.

3. Track your “showed up” days

Start a log like:

📅 2025-06-13 — Showed up
🧠 Burned out. But opened VS Code. Fixed tiny bug.  
Not much… but I didn’t ghost myself.

Over time, you’ll see your true consistency — not just outputs, but persistence.

❤️ Final Thought

You showed up today.
Even with brain fog. Even with nothing left.
That’s not failure. That’s grit.

Keep showing up — not perfectly, but honestly.
You’re building something bigger than code.

💭 “You Were Never Lazy…” — A Quiet Truth for Burnt-Out Devs

Rvn — Sun, 15 Jun 2025 05:45:47 +0000

💭 “You Were Never Lazy…” — A Quiet Truth for Burnt-Out Devs

🤯 What if your problem was never laziness…
What if you were just trying to scale alone?

😓 Burnout ≠ Laziness

We’ve all been there.

You open your editor — and just stare.
A bug from yesterday still lingers.
You’ve been pushing late nights, endless context-switching, and shipping under pressure.

And when your mind and body finally say “no more”, you don’t feel tired.
You feel lazy.

But here’s the truth:

You weren’t lazy.
You were exhausted from solving everything alone.

🧠 Even Code Doesn’t Work Alone

Here’s the kicker: even the most basic code functions don’t run in isolation.

Think about .map().

[1, 2, 3].map(num => num * 2)
// → [2, 4, 6]

It asks for help — from a function you give it.
It scales its effort by delegating.

That’s how most of code works:

Frameworks abstract the hard stuff
Helpers reduce repetition
Collaboration makes ideas real faster

So… why do we expect ourselves to work alone 24/7?

🧩 The Hidden Cost of Solo Mode

Being a dev often means:

Wearing multiple hats (frontend/backend/devops/docs/client support…)
Learning while building
Debugging alone at 2:43 AM
Saying “I got it” when you don’t

This “solo hero” mindset creates guilt when we stop —
But that guilt isn’t productive. It’s corrosive.

Because if we confuse burnout for personal failure,
we’ll keep pushing until we break.

💬 What Help Actually Looks Like

Asking for help doesn’t mean you’re incapable.
It means you’re building like a dev — efficiently.

Real-world examples:

✅ You ask a teammate to pair-program for 20 minutes
✅ You check Stack Overflow instead of brute-forcing
✅ You use useEffect with a custom hook someone already made
✅ You say, “I don’t know yet, let me ask the team”

These aren’t weaknesses. They’re strategies.

It’s not cheating.
It’s scaling.

🧘 Final Thought: Grace for Your Developer Self

If your brain is foggy, if your body’s done,
it’s not because you “don’t want it enough.”

You’ve just reached a limit — and limits are data.

So pause.
Ask.
Lean on the system.

Because the moment you ask for help isn’t when you fail.

It’s when you start scaling.

🚀 17 and Full-Stack: My Dev Journey So Far

Rvn — Mon, 09 Jun 2025 14:48:27 +0000

Hey dev.to 👋
I'm Ravan, a 17-year-old full-stack developer who's been deep in code for the past 10 months.

Since I started, I’ve spent over 3000 hours learning, building, and breaking things on purpose — just to understand how they work. I’ve written over 100,000 lines of code, mostly across full-stack projects.

My main stack:

Vue, JavaScript, TypeScript, Node.js, and sometimes Python, Java, or raw HTML/CSS when needed.

I care a lot about:

🧠 Writing clean, maintainable code
🛠️ Building scalable backend architectures
🔍 Debugging smarter, not harder
💡 Turning ideas into real, working systems

Outside of coding, I enjoy thinking about strategy, leadership, and systems — stuff I believe overlaps with building good software.

I'll be sharing things I learn here:

Dev experiments
Coding techniques I find useful
Thoughts on mindset and growth as a young dev

I’m still early in my journey, but I’m moving fast — and I’m here to learn and contribute along the way.
