I have been working for the Wikimedia Foundation since July 2011, initially as a contractor supporting movement communications, and becoming a regular employee in May 2012. See also my staff page on the WMF wiki.
As a volunteer, I have been contributing to Wikimedia projects since 2003. IRC (Freenode): HaeB
Some technical notes, mostly for myself:
Although I work for the Wikimedia Foundation, contributions under this account do not necessarily represent the actions or views of the Foundation unless expressly stated otherwise. For example, edits to articles or uploads of other media are done in my individual, personal capacity unless otherwise stated.
