Dan's haven

I am Dan Čermák a Software Engineer working on Development Tools at SUSE. Besides improving the developer experience, I'm also very passionate about testing & QA, documentation, automation and community building.

I am active in the Fedora community, where I am a package maintainer, one of the founding members of the i3 SIG and I also served in FESCo for the Fedora 34 cycle.

When I'm not sitting in front of the computer, I enjoy baking and cooking and a nice bike ride or a workout.
