My name is Derk-Jan Hartman. I used to edit, but now I mostly deal with tech stuff. I'm an administrator on English Wikipedia and used to be one on Commons. I'm a volunteer contributor to the MediaWiki software that runs Wikipedia, dealing with things like accessibility, scripting, CSS, small bugs, mobile, video and so much more.. A long time ago I was one of the volunteer developers of VLC media player.
