Senior-led AI delivery
How we work
A repeatable loop — brief in, production out, in days not sprints.
- 01Brief & scopeA senior scopes it into a fixed deliverable and sets the architecture and bar.
- 02Directed AI buildSenior-written prompts drive parallel agents — code, tests, docs — toward the right design.
- 03Automated verificatione2e + API tests and demo data prove correctness — never "works on my machine".
- 04Senior sign-offA senior makes the calls that matter: right solution, production-quality, ship.
- 05ProductionCI gates quality. You get a working product, not a Jira ticket.

From clients
What they said
They scoped it in one call, shipped a working demo in the first week, and had it in production before I expected to have even finished briefing another agency.
I was skeptical about AI-built code quality. The test coverage and demo environment they shipped on day one settled that immediately.

FAQ
Questions you're probably asking
Is AI-built code actually reliable?
Every feature ships with automated end-to-end tests — including UI — plus demo data. Quality is gated in CI before anything reaches production. You can run the tests yourself on day one.
Do I own the code?
Yes, fully. No lock-in, no proprietary runtime, no subscription required to run what we build. You get the repository, the deploy config, and the keys.
What if the job is bigger than one module?
We scope it into fixed stages. Start small, validate the outcome, then expand only if it works. No big upfront commitment required. Each stage is a fixed price and a working deliverable.
Who maintains it after?
You can — it's documented, tested, and written in mainstream TypeScript without exotic frameworks. Or we can, on a retainer. Your choice; you're never stuck with us.
What if I'm not happy?
We offer a money-back guarantee on the first milestone. If the deliverable doesn't meet the agreed spec, you don't pay.
