About Me

"You can always improve yourself"

I've been programming since 2000, starting purely as a hobby. Some early pet projects:

  • Own OTS (Open Tibia Server) with custom spells in Lua
  • A file batch renamer using regex
  • A DotA champion lore app in Java

Degrees

🎓 Computer Engineering
🎓 Technology in Systems Development & Analysis

Currently at Underwork, focused on Web and hybrid mobile apps — mostly React Native and Flutter. Fell in love with Android since Froyo and that knowledge proved invaluable when bridging native Android and React Native.

Next goal: a Master's Degree in AI. Always fascinated by it — currently self-taught in the area.

What I Love Building With

K

Kotlin

My Android journey started with Froyo and Java, but Kotlin changed everything. Its expressiveness, null-safety, coroutines, and extension functions make Android development genuinely enjoyable. It's the language I reach for when I want code that reads like intention.

L

Laravel & Filament

★ Filament

Laravel is what made me fall back in love with PHP. I've been a heavy contributor to the ecosystem — including packages in the modular architecture space — and rely on Filament for building complex admin panels and CRUD-heavy dashboards with elegant, maintainable code. The broader ecosystem (Forge, Vapor, Horizon) lets me ship production-grade backends fast, and I maintain a personal starter template with event-driven architecture baked in.
