You know what to build. You do not have the team to build it.

The spec exists, or close to it. Hiring the team to build it takes months you do not have, and the agencies you have talked to quote phases and send decks. What is missing is not a plan. It is a team that starts.

The architecture is written down in the first week, in a document you keep. The repository lives in your accounts from the first commit, so ownership is never handed over, because you always had it. A working slice of the product ships every week; you click through it and tell us where it is wrong. Scope is fixed before we start and defended after: new ideas go on a list, not into the build.

The codebase, in your organisation, with history intact. The architecture document. CI/CD that deploys on merge. Tests that run and mean something. A runbook your next engineer can operate from. And a final week where your team drives and we watch, because a handover you have not rehearsed is a promise, not a handover.

TypeScript, React, Node.js or Go, PostgreSQL. Not because they are exciting, but because your next hire already knows them, the failure modes are documented, and nothing in the stack depends on us staying. The technology choices are part of the handover.
