## about

i like solving interesting problems and building fullstack stuff, like this site.

outside of work it's mostly side projects, sometimes just to learn something new. the rest of the time i'm lurking on twitter and experimenting with whatever catches my eye: ai, 3d, some low level stuff. i still care a lot about quality, which feels like a niche hobby in the age of ai slop.

## work

- software engineer @ big eu tech company, 2025 — now. mostly backend stuff that gets a lot of traffic. i end up on the frontend too when something there needs fixing, so fullstack-ish.
