// FLIGHT PLAN — HOW A PROJECT RUNS

Five stages, start to launch.

01

Discover

Scope the problem, map data flows, agree what "done" looks like.

02

Design

Schema, API contracts and UI flow, reviewed before a line of code.

03

Build

Backend, frontend and database work in parallel sprints.

04

Test

Load, edge cases and real data — not just the happy path.

05

Launch

Deploy, monitor, stay on for fixes as real usage hits the system.

Have a system that needs building, fixing, or scaling?

Tell me what you're working with — a rough idea, a broken legacy system, or a full spec.
