I build software that solves real problems. I started at 13 out of curiosity; today I work remotely as a full-stack developer and I run several SaaS with various paying clients and daily active users.

§ 01 — Manifesto
What drives me isn't the stack. It's the problem. I like to understand the problem very well — and the solutions — before opening the editor.
§ 02 — How I work
A guy who builds.

Obsessed with the problem
Understanding the problem well is half the journey.

I started before AI
I learned alone, out of curiosity. Today I learn what the project needs, at the speed it needs.

§ 05 — How I work
Obsessed with the problem
In everything I do, I always look for a way to solve a problem or make something easier. My biggest SaaS was born when I saw that the school librarian was keeping records on paper. Today, Bibliotech is the only system for school libraries where every student can see all the books in their school library in the palm of their hand, and reserve them from there. I have several more projects I built the same way on my GitHub!
