Since 2013 I am a webmaster on drupal.org. My webmaster Bio: http://fromwaydowntown.de/en/article/webmastering-drupalorg

I was member of the DSWG Community Tools Leadership team as the Planet Drupal section owner (https://groups.drupal.org/node/418338) until it was disbanded.

Mostly I am strolling through the issue queues of modules I am interested in triaging or testing patches.
I have provided translations and work on docs from time to time. Once in a while I take the big broom to the core queue. I was part of the Media Support Squad.
I was especially interested in promoting and improving node_gallery for D6. I am very thrilled that there is a working D7 version now.
I am no good at coding, yet was ranked decently by certified to rock: http://certifiedtorock.com/u/412465 (careful: historic data).
