Been involved in open source for 20 years.
Currently QtJambi maintainer (the Qt framework for Java, which combines the best of both worlds). This is a Qt/C++/JNI/Java project and is over 250k LoC. We are always looking for more contributors with the project.
Previously worked with and on various OSS projects (Linux Kernel, ZMailer, OpenSSL, ...)
Spend most of my time making OSS do what I want (or rather what my clients want open source to do for them)
