Jonas Hahnfeld’s 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.
