I’m a newsroom developer at the Financial Times. Previously I’ve worked at the Guardian, the Bureau of Investigative Journalism, and Ordnance Survey’s Geovation Hub.

I also co-run Journocoders, a community of journalists and other people working in the media interested in developing technical skills for use in their reporting.
