About Me

Hi, I'm Stephan. I'm an independent software architect. I focus on building backend systems with highly scalable and distributed characteristics.

I like to experiment with different programming languages and learn from different paradigms such as imparative and functional styles. My main proficiency is in C# and .NET and I enjoy using other languages such as Go, F# and Rust even some Elixir from time to time.

When I'm not working, I like to have a fun time with my kids. I really enjoy travelling the world and experiencing new cultures.
