I decided it was too hard to work out your dress size in different shops. So I built an interactive visualisation to make it easier, using D3.js.
It was featured in the Guardian, Daily Mail, the Economist, the Wall Street Journal, BBC television and many other places.
I made the folios of Domesday Book freely available online for the first time, and built an elegant GeoDjango interface and API.
The BBC wrote about it, and the British Museum now uses the API. The site has around 130,000 unique users a year.
I wondered how travel time to London affected house prices. So I calculated it for UK stations and graphed the commuter zone visually.
Search it to see your nearest station, or find out more about it from Nestoria or Kasabi.
I got frustrated by not being able to find the kind of shoes I wanted online. So I built a search engine for shoes.
You can use it to search more than 20 UK stores, from Anthropologie to Zara.
Back when Android was brand new, I decided what it really needed was an 18th-century-style notebook app.
Before I retired the app in 2012, more than 330,000 people had downloaded it, and it had an average rating of 4.3 stars.
I'm a volunteer at democracy charity mySociety, and I wrote the original Android app for the FixMyStreet project.
It was downloaded by over 6,400 people. An open-source project, it was used as the basis for versions in Ireland, New Zealand, and Norway.
Funnel plots are a great way to show uncertainty visually. At an NHS Hack Day, I built a simple tool to turn spreadsheets into funnel plots.
It needs more work! The code is MIT licensed and available on GitHub.
In April 2012, my work on CycleStreets Mobile won "Best Lightweight Application" in Jakob Nielsen's user interfaces of the year.
As a freelancer, I've worked with large companies, non-profits, government and startups. Corporate clients include Marks & Spencer, think-tank RAND, Channel 4, and barristers' chambers 4 Pump Court. Startup clients include Axon Active, Nestoria, ElasticHosts,
IntelliSense, and ScraperWiki. Non-profit clients include CycleStreets and the Open Knowledge Foundation.
I studied English and computer science at Cambridge, worked in the City of London, and then became a full-time coder. Full CV on LinkedIn.
