Welcome to my personal page!

You can find most of my coding activites for open source projects on GitHub and GitLab. I'm actively working on LilyPond with the development repository at lilypond/lilypond.
In the past, I've contributed to Clang and the OpenMP runtime (commits in llvm/llvm-project) as well as some patches to the Linux kernel.
