Admin on the English Wikipedia, MediaWiki.org, and Meta. Like tidying up very old forgotten tasks to hopefully bring them to people's attention. My other niche is working with obscure WMF-deployed code no one else is maintaining.
Specific things I've worked on at one point or another:
- MediaWiki-extensions-Babel
- MediaWiki-extensions-Newsletter (originally as a Google Code-In project, still poke at it periodically)
- MediaWiki-MergeHistory
- MediaWiki-extensions-LabeledSectionTransclusion
- MediaWiki-extensions-GuidedTour
- Phabricator translations
