№ 02 — How it works
Three weeks* from brief to live.
Step 01 — Week 1
Brief & scope
A short call, a written brief, a fixed scope. After we are left with a clear path towards the goal.
Step 02 — Week 1-2
Build & preview
You get a live preview URL on day two and watch it grow — no static handoffs, no surprises. Feedback goes in, the same day, on the real thing.
Step 03 — Week 3
Ship & hand off
Production deploy, a clean repo, documented stack, and two weeks of post-launch support included.
