English: Hi, I am German Wikimedian from Munich.
I started off as a German Wikipedian (where I'm a sysop and was a oversight), but now I'm a cross-wiki contributor. Beside Wikipedia, I'm an OTRS volunteer and a MediaWiki developer, though I spend little time developing these days.
See my meta user page for more information about me.
If you want to leave me a message, you can do so at my commons talk page or my meta talk page.
My work on Wikimedia Commons
I occasionally upload images or fix existing ones. Sometimes I also fix vandalism.
One image I uploaded, File:Big.Buck.Bunny.-.Frank.Rinky.Gimera.png, is featured on the German Wikipedia (although credit doesn't belong to me – I merely selected a frame from the HD version of the film for a screenshot).
