Developer building small, fun, and useful apps

I turn ideas into working software — whether tracking my runs or building games to play with friends. I build things to learn, to solve problems, and mostly because it's fun. AI has become a big part of how I develop, letting me move faster and tackle more ambitious ideas.

I build things because I enjoy it.

I'm a developer who loves building side projects — from fitness trackers to party games. My work is driven by curiosity and the pleasure of making something from nothing. I care about clean code, good UX, and actually shipping things.
