My name is Karl and I am a Software Engineer from Germany.

My main focus is on platform architecture and automation of infrastructure, security and compliance. I am employed at Klarna in Berlin.

Some technical principles/philosophies I fancy include UNIX, Immutability and KISS. However, above all stands pragmatism because I haven’t seen the silver bullet yet.

In my free time I enjoy working on IoT projects, i.e., soldering prototypes, designing PCBs and programming MCUs. Further, I like nix, try coding in go or rust and am repeatedly overwhelmed and humbled by the unlimited knowledge of the open source community.

Apart from technical stuff, I practice QwanKiDo, try to learn Mandarin Chinese and like to play classical guitar.
