Some of the work I did in the Wikimedia universe:
I was one of the initiators of Wiki Loves Monuments and helped it scale internationally (2010-2013). Since its initiation, the project has been organized in over 70 countries, and collected more than 1.7 million photos of built cultural heritage worldwide, submitted by 45,000+ people. In 2017, I'm back on its international team.
I like to encourage discussion and knowledge sharing, and for that reason I collected and presented the Coolest Projects of Wikimedia Chapters in 2011, and presented them at Wikimani, the annual Wikimedia Conference. I repeated this in 2012 and 2013, and Deror continued the tradition since then.
Over the years, Wikimania turned into a presentation-heavy conference, and in 2014 I took the initiative to bring back more discussions, by requesting, organizing and coordinating a separate track of discussions together with Iopensa in what we called the Discussion Room. This has become a full track of the conference, and roundtable, community focused discussions are back in the spotlights.
Over the years, I have started or heavily contributed to over 750 articles, mostly on the Dutch Wikipedia. I like to focus my efforts on translating and checking biographies, or writing reasonably short biographies from scratch. In total I have made more than 40,000 edits on the various projects.
