Hi, I'm Gregor.
I live in Slovenia and I'm curious by nature. Building software is how I scratch my own itches: when an app doesn't do quite what I want, I make one that does, and learn something along the way.
I care about things that feel fast, look calm, and keep working when nobody's watching. If I build something, it's because I'll use it every day.
When I'm not building, I'm usually deep in whatever caught my attention this week: sports, video games, the tech world or just about anything.
Things I've built
Mostly for myself, sometimes for the people around me. Most are private, so here's what they do instead of the code.
