Projects

Things I've built for fun outside work.

  1. Flights

    The world's flight network, 89,000 routes between 3,830 airports, on a split-flap departures board you can search by airport or airline.

    The preview shows a dark world map built from grey squares, brightest where airports cluster, with yellow route arcs between cities and a departures board below listing Shanghai, Chengdu and Chicago as the airports with the most routes.

  2. The Satellites in Our Skies

    Every satellite put into Earth orbit since 1957, on a 3D globe you can scrub through time.

    The preview shows Earth wrapped in satellites drawn as coloured points, a count of satellites in orbit by orbit type, and a timeline from 1957 to 2000.

About

I'm a software engineer, mostly on the frontend, with experience across the full stack. I'm particularly interested in front-end performance, building interfaces for unconventional form factors, and maximising walk-up usability.

Outside work I'm usually training for a triathlon, or in the sea surfing, paddleboarding or just swimming.

I write occasionally, about careers, university and experiments. Read the blog

Say hello

I'm not currently looking for new roles, but I read everything sent my way and aim to reply within a few days.

Or find me on LinkedIn and GitHub.
