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.)
Please ask general questions in the corresponding and dedicated support channels instead of sending me personal emails or editing my personal talk page.
