I work for W3C from home in Whistler, Canada, operating out of the MIT/CSAIL site, on contract through my consulting company impressive.net, Inc.
Along with the rest of the Systems Team, I help manage W3C's technical operations: web servers, email servers, mailing lists, publishing tools, user accounts and support.
Recently I have been focused on improving our email infrastructure and mailing list system. In the past I was responsible for the HTML validation service.
My personal web site has much more information about what I do in my spare time, including travel (sometimes written about in my travel blog), photography, and writing software.
