About

I'm a software engineer based in Slovenia. I'm interested in all things related to computers. This means that I put up with computers for a living, and also just for the fun of it!

Most of my day-to-day work is backend engineering. In my spare time I love working on side projects, which have lately been drifting more towards systems programming. I also spend way too much time tinkering with my setup and self-hosting.

If I'm not behind a computer, you'll find me spending time with my beautiful wife and two children.

On this page I write about the side projects that I am working on and random thoughts about computers that pop into my head.
