Build

Custom software

Most teams do not need more prototypes. They need software that holds up under real users, real data, and real money. We build the whole thing — product surface, API, data model, deployment — and we hand it over with tests, docs, and a runbook so your team can take it from there.

Deliverables

What lands in your hands

Not a phase list. These are the artefacts you own at the end, and the ones we are prepared to be measured against.

  • 01

    A working product in staging within the first month, not a slide deck

  • 02

    TypeScript codebase on Next.js, React Native, or Node — yours, in your repo

  • 03

    Schema design, migrations, and seed data on Postgres

  • 04

    CI/CD pipeline, staging and production environments, and rollback you can trigger

  • 05

    Test suite covering the paths that lose money when they break

  • 06

    Handover docs, architecture notes, and two weeks of paired support after launch

How we work

The same four stages, every time

No discovery phase that never ends, and no black box between kickoff and launch.

Read the full process
  1. 01Week 1

    Scope

    We map the problem, agree what version one must do, and cut everything it does not. You leave the week with a written scope, a fixed price or rate, and a delivery date we are willing to be held to.

  2. 02Week 2-3

    Design

    Flows, screens, and data model in parallel. You review clickable work, not static mockups, so the arguments happen while changes are still cheap.

  3. 03Week 4+

    Build

    Two-week sprints with a demo at the end of each one. Staging updates continuously, so you can use the product long before it launches.

  4. 04Launch +30d

    Ship

    We deploy, watch the graphs, and fix what real traffic exposes. Thirty days of included support, then handover docs — or we keep going as your team.
