Who I am and why I still do this

Started early. Never stopped. Still enjoying it.

Straight to the point

No BS. If something doesn't make sense, I say it. If there's a better way, I show it.

Results above all

Doesn't matter how "pretty" the code is if it doesn't solve the problem.

I see patterns

Before it becomes a problem, I already saw where it'll break.

Fast learner

New stack? New domain? Give me a week.

No half measures

If it has my name on it, it works properly.

Pragmatic

Over-engineering is as bad as bad code. Every decision has a reason.

I deliver what I promise. It works. It scales. Next problem?

TL;DR

I build systems that work. Solve complex problems. Deliver results. And yes, I still enjoy it.

[ The Approach ]

Systems are made of decisions

Every line of code is a choice. Every architecture solves a specific problem. There's no perfect solution — there's a solution that makes sense for the context. My job is understanding the context, anticipating problems, and building something that scales.

[ The Result ]

Technology that solves real problems

In the end, code is a tool. What matters is impact: system running, user satisfied, problem solved. I build experiences that work — and keep working when nobody's watching.

Anyone copies tutorials. AI generates boilerplate. But architecting systems that scale? Anticipating problems before they appear? That's not taught on YouTube.

The Beginning

Curious kid taking things apart to understand how they worked. First time with tech. Love at first sight (or bug).

2014

Hello World

First line of code. First bug (obviously not mine). Discovered making computers obey was better than any game.

2021

Production

Real projects. Servers running. Users using. That feeling of seeing your code working for real? Addictive.

2025

Today

Breaking code (on purpose now). Solving bigger problems. Building better systems. Still enjoying it.

Nowthatyouknowme,let'sgettothetechnicalpart.(Yes,there'shumorevenhere.)

Before talking about what I do, let me show you how I think.

Constant movement. Clear purpose. Consistent execution. That's what drives me.

Full Stack Developer | Systems Architect

I don't measure knowledge in percentages

"I know React 85%" or "Python 90%"
that means nothing.

Why?

01

There's always something new

Tech changes fast. Those who think they know everything are already outdated.

02

Context is everything

Knowing how to make an API doesn't mean knowing how to make one that handles 1M req/s.

03

Results > Certificates

What matters is what you deliver, not how many courses you took.

So, what do I use?

Real stack. No fluff.
