Discovery
We learn the problem, the constraints, and the people who'll use what we build.
Design
Structure first — information architecture, flows, and interface decisions that hold up.
Build
Clean, typed, tested code. Shipped in increments, not a single drop at the end.
Launch
Deployed, monitored, and handed over with documentation — not abandoned.
