What I've built.

Eight products I've taken from the first idea through to live, making the decisions about how each one should work and testing every section myself. They're all running, so feel free to try them.

Selected work

Vantage City OS

vantage-city.dev

A live 3D map of London drawn as holograms, built on Ordnance Survey and open data

Vantage City OS over Southwark and the City of London: glowing cyan 3D buildings along the Thames, a route line across the river, floating panels for Tube line status and a routing comparison scored on air quality, and side panels showing the borough and ward from Ordnance Survey boundaries, land cover, air quality and weather.

On this site

Fit Check

Paste a job ad, or a link to one, and three AI agents check it against everything on this site, coordinated by an orchestrator you can watch working. It tells you where I don't fit as well as where I do.
