I'm a computer programmer and a climber. I work as the Technical Director of Loco2 where I try to make it as easy as possible for people to take a train rather than a plane.
After spending far too much of my life in the rather flat South East of England, I now live in Llanberis, North Wales, at the foot of Snowdon.
I like climbing a lot, and spend most of my spare time doing it. I write a blog about my trips.
I used to do lots of open source programming, but climbing has taken over these days. I was on the Ruby on Rails core team and I started the Poltergeist and Spring projects.
In the past I wrote some programming articles on this website.
