Background

About

I'm a CS teacher based in Austria.
I build open-source education technology, automation tooling, and Linux desktop apps.

If I'm not teaching, I'm probably automating something that didn't strictly need it.

I'm a father of three. I wingfoil, snowboard, and I'll try just about any other sport that involves a board. I practice yoga, and I play guitar or piano when I need to clear my head.

I'm convinced knowledge and software have to be free and that your data has to be protected.
I also work from the idea that nothing is impossible — in the classroom and in code.

Open Source First is how I put that into practice: everything I publish is free, and it will stay that way.
