Four Stations, No Guesswork

Each build passes through the same four stations of the workshop. Nothing is signed off until the tolerance check is signed with it.

Station 01

Draft the Drawing

Scope interviews, data model sketch and a written specification with measurable acceptance criteria.

Duration: 3–5 days
Station 02

Cut the Prototype

Working skeleton with real screens and seeded data — you click through the machine before we machine the rest.

Duration: 5–10 days
Station 03

Harden the Assembly

Tests, accessibility passes, load shaping and security review run against every merged branch.

Duration: 5–12 days
Station 04

Sign & Hand Over

Deployment, runbook, repository transfer and a 30-day warranty window on the delivered build.

Duration: 2–4 days
Requisition desk // Sheet 3

Bring us the drawing. We will build the machine.

Send the scope, the constraints and the deadline. You get a written work order with price, tolerances and a delivery date within two business hours.
