Free software

Most of the projects I've contributed to can be found on github. A few highlights:

  • pywikibot, the Python Mediawiki Bot Framework. Continued involvement in development since 2006.
  • Gerrit Reviewer Bot; a tool which adds reviewers to patches in Gerrit based on subscriptions on a wiki page. Helps get patches reviewed quickly on Wikimedia's Gerrit since december 2012.
  • Gerrit Patch Uploader; Flask website which uploads changesets to Gerrit for you. Gerrit has a steep learning curve, and this helps new contributors to join Wikimedia related development quickly.
  • flask-mwoauth; Flask blueprint to connect to Mediawiki OAuth providers.
