I don't just write code.
I build the whole thing — from the API to the interface —
until it's exactly the way it has to be.

About

Developer from Maceió, Brazil. Started with backends and fell in love with the full picture — not just the logic behind the curtain, but the interface that makes it usable and the design that makes people want to use it.

Off the code: single-player games, music while working, and building my own game in Godot. Perfectionist by nature — I don't ship until it's right. Currently studying Systems Analysis and Development at CESMAC.
