I am an Infrastructure Engineer and Debian Developer from Germany with a focus on DevOps and Infrastructure, Engineering Culture and People. I'm also keeping large portions of legacy infrastructure alive. Back in the old days I was an IPv6 evangelist, and I'm still responsible for some BGP-4 border routers.
In 2024/2025 I had a sabbatical and traveled a bit around the world.
