Mobile: +44 (0) 782-414-2319


I am a software engineer with over 8 years of experience in frontend and backend web development, data engineering and machine learning. I am passionate about agile development, continuous integration and code reviews. I am interested in open source, open web standards, and digital rights protection.

In my spare time I organise events for the geek community, including BarCamps, HackDays and Geek Trips. I like to present on Git, Ruby, testing frameworks, and photography. My most successful hacks include a browser extension for donating to charities, and a mobile version of the BBC/British Museum's "A History of the world in 100 objects" programme.
