I'm a freelance software developer from Berlin, Germany. Most of my paid projects won't be published as free software but all do you use/rely on some open source software. And my preferred software stack for doing development is Python and Fedora /CentOS /Red Hat Enterprise Linux .
Therefore contributing to free software projects is a good way to ensure that annoying bugs will get fixed soon and that the features I need make it into the main distribution (so that I don't have to maintain local forks). And of course, free software coding is really fun!
Paul Howarth was so kind and sponsored me as a Fedora developer. Furthermore he patiently helped me with all my beginner problems. Thanks again, Paul!
