My name is Johan Jönsson. I'm mainly active on Swedish Wikipedia and Commons, but I edit a fair number of wikis on a semi-regular basis. When I'm not editing Wikipedia (or other Wikimedia projects) for fun, I work for the Wikimedia Foundation. My WMF account is Johan (WMF).
I'm here to help out in various capacities. My main interests for the upcoming Wikimania in Stockholm (2019) is to engage Swedish Wikimedians and other relevant local actors and make them come and take part of the conference, as well as helping out with the hackathon.
