Things that I'm interested in, interest me.

About me

I am a digital enthusiast from Switzerland who never stopped being interested. Computers, Smartphones, Software - all things that I really enjoy. Not just as a consumer, but also as a creator. In my free time I love to create my own programs or improve upon existing open-source projects. I love discussing the newest technology trends with friends and work colleagues. I love unwinding and playing a few video games. I love finding new interesting things.

My goal in life is to never stop being interested in interesting things. That's why I made it my bio all over the internet: Things that I'm interested in, interest me. Oh, and I also want to see Northern Lights once :)

I run a (mostly) software-themed blog over at
