In short

These are 48 write-ups from the 360+ projects we have delivered since 2012. They cover new builds, takeovers of existing code and senior engineers joining in-house teams, for clients in health, retail, transport, finance and entertainment. Each one says what was broken or missing, what we built, how long it took and what changed after launch.

Selected work

Four projects, four ways of working

A product built from scratch with AI coding agents, a legacy platform modernized without a feature freeze, an app re-scoped into a #1 hit, and a launch watched by 2 million people.
