I'm a Wikipedian mainly active on de.wikipedia and Wikimedia Commons, but also on Wikidata and sometimes on en.wikipedia. I'm a sysop and mentor on de.wp assisting new wikipedians on their first steps and autopatrolled on Commons. Furthermore I'm involved in teaching how to edit Wikipedia to specific audiences and organizing Edit-a-thons, e.g. telecommunication history and technology or recently Wikipedia for Peace and the German-French Edit-a-thon at the Frankfurt book fair both in 2017. I'm a licensed amateur radio operator, studying Philosophy, Political science and Life sciences (biology) at the university and I'm involved in (digital) art projects as technical consultant. Open access to Data in general is also part of my activities in local and international communities providing access to meshed networks (with and without Internet) for people in need of information and means of communication. (e.g. WinLink, Freifunk)
