I follow MediaWiki development since 2007. Although I don’t regularly submit patches for the MediaWiki core, I act as an ambassador, submitting bugs, helping in their resolution, exchanging with the French-speaking community, improving documentation and its translation into French, etc. I developed three extensions (BackwardsTimeTravel, HSTS, and MediaWikiFarm).
Since 2016, I run a small MediaWiki consulting company in France, which help companies, associations and public sector to set up MediaWiki installations.
