Hello, I'm Wiki13 from the Dutch Wikipedia.
Globally I primarily deal with anti-vandalism work as part of SWMT. I'm a global rollbacker and a former global sysop (due to time constraints in the past). I am also a former administrator on Wikidata (Fun fact: I actually was one of the first to be appointed by the community), where I helped in the early days to get Wikidata close to the level it is nowadays, a full fletched wiki project with it's own oversighters.
My native language is, obviously, Dutch, but I can also understand Afrikaans and English.
