Small software, games and the web
I build things that fit in kilobytes: games that draw every pixel in code, iPhone apps that work offline without ads, and web apps with as few dependencies as possible. This is where I write down how they are made and what I learn on the way — including where AI helps and where it doesn’t.
Games I made
All projects
Breakup
A neon brick-breaker played as a roguelite, written in C with SDL3: towers instead of walls, perks, bosses and a daily run that needs no server.
