Applications built to be maintained
Web and mobile applications delivered by a small senior team, with tests, documentation and a deployment pipeline handed over at the end so you are never held hostage by your own product.
What we do
01
Product engineering
React, TypeScript and modern backends, built for the load you actually have.
02
Mobile
iOS and Android delivery through to store submission and release management.
03
Testing and CI
Automated tests and pipelines so releases are routine rather than events.
04
Handover
Documentation, runbooks and access transferred in full at close.
