How it works
A small studio, a clear process
You always talk to the person writing the code, and you always know what ships next.
- 01
Discover
A short call to pin down the goal, the constraints and what success looks like in numbers.
- 02
Design
A written architecture and plan with trade-offs, milestones and an honest estimate.
- 03
Build
Small, working increments in your repository, with a demo every week instead of a big reveal.
- 04
Operate
Monitoring, runbooks and documentation, then a clean handover or ongoing support.
