hey

Developer and sysadmin who builds Android apps, websites, Discord bots, APIs, admin dashboards, and whatever else seems fun to implement. Started with simple automation scripts and somehow ended up running entire self-hosted infrastructures.

Into self-hosted homelabs (because why pay for cloud when you can maintain servers at 3am?), Android custom ROMs and app development, game server hosting, mail servers that actually work, and web development with modern frameworks.

Python + Flask is my go-to for backends. Keeps things simple and lets you move fast. Flutter when I need cross-platform UIs because writing the same app three times is not my idea of fun. Docker for deployment because "it works on my machine" stopped being an excuse years ago.

This site? Built with Astro. Static site generator that doesn't try to be everything. Just does its job well.

projects

Built Discord bots that actually do useful stuff, admin panels that don't make you want to cry, image galleries for personal use, and a bunch of self-hosted infrastructure that somehow stays running.

Most projects start with "wouldn't it be cool if..." and end up being way more complex than initially planned. But that's half the fun.

when i'm not staring at terminals

Family time is important. Can't spend all day in front of screens.

When I actually leave the house: cycling, swimming, basketball. Turns out physical activity is good for you. Who knew.
