Hi, I'm John Tobin.

Since July 2010 I've been working as a Site Reliability Engineer for Google. Currently I run Colossus; previously I ran BigTable and GFS.

I'm a double graduate of Trinity College: I completed a B.A. (Mod) in Computer Science in 2002, and an M.Sc. in Computer Science in 2009; my thesis and papers are available from my publications page. I studied for my M.Sc. in evenings and weekends, in addition to my full-time job, and completed it in two years, the minimum time period permitted.

For seven years I was a Unix Systems Administrator in the School of Computer Science and Statistics, Trinity College Dublin.

For four years I was a Unix Systems Administrator for the Internet Society, Trinity College Dublin.
