Open Source

I’m a strong believer in open source and therefore support it.
Right now I’m a committer and PMC at the Apache Karaf Project and comitter of the OPS4j Pax Web Project. where I also toke over the Project lead since it was kind of abandoned. Since May 2014 I’m a member of the Apache Software Foundation.
