MediaWiki

I have been working with MediaWiki, the software behind Wikipedia, since 2009. During these 10+ years I have worked for several companies across the globe, including Google and the Wikimedia Foundation. Between 2012 and 2019 I worked for Wikimedia Deutschland as software architect, primarily on the Wikidata project. I created over a dozen MediaWiki extensions, contributed to many more and am one of the maintainers of Semantic MediaWiki.
