I joined the Wikimedia Foundation in October 2012. My main focus has been managing software bug reports and enhancements requests in the Wikimedia bugtracker (Phabricator). See mw:Bugwrangler for more information. Furthermore, I am also involved in maintaining metrics about Wikimedia's technical community and co-organize Wikimedia's participation in Google Code-In. There is a list of Phabricator tasks that I currently work on or plan to work on. I read a lot of bugmail.
(Until 09 January 2013 I just had one user account, Malyacko, for my personal and staff edits.)
