I was the guy that started working on TenDRA in the beginning of 2002, 4 years after DERA abandoned it. After 5 years I've handed the project over to someone else and am not involved anymore.
I have been a committer on the FreeBSD project.
I have been a committer on the DragonFly BSD project.
I have been a committer on the Trac project.
I work on and have contributed to a lot of open source projects in the form of bug fixes, portability fixes, documentation and feature patches.
