👋 Hi!

I’m a software engineer specializing in server applications and system-level software development, but sometimes I venture into the front end world too. Quite often I find myself taking a deep dive into a topic that tickles my brain.

When I’m not coding I like spending time outdoors, such as cycling, climbing. We are writing this blog together with my partner Sanja.

You can find most of my work on GitHub.
