I work at elego, actively supporting and developing Subversion, a well-known version control system maintained by the Apache Software Foundation.
I graduated in computer science at the
Free University of Berlin
(BSc Thesis)
where I'm also a member of spline.
I also obtained an MSc degree in software development for computer
networks at University College Cork.
I use and contribute to OpenBSD.
As part of my MSc studies at UCC I contributed to
ospf6d,
which is an implementation of the OSPF routing protocol for IPv6
(see RFC5340).
I was involved in dslinux but the project is not actively being developed anymore.
I also make music occasionally.
A couple of small programs I've written mostly for fun can be found here.
