How we deliver

From specification to production

The same five steps on every engagement, so you always know what comes next.

  1. Step 1

    Discover

    We learn the product, the users and what must never go wrong, then write it down as a specification.

  2. Step 2

    Design

    Architecture, threat model and a scoped plan with milestones, reviewed with you before code.

  3. Step 3

    Build

    Small, readable components with tests in every pull request and a demo at each milestone.

  4. Step 4

    Test & review

    Invariant fuzzing, static analysis, fork tests and manual review. Findings arrive as tests you can run.

  5. Step 5

    Launch & support

    Deployment scripts, key ceremonies, monitoring and a runbook. We stay on after launch.

Senior engineers, start to finish

The engineers who scope your project are the ones who design and build it. Nothing gets lost in a hand-off.

Security from the first commit

Written specs, invariant tests and fuzzing are part of the build, not a step bolted on before launch.

Clear scope, no surprises

A written scope with assumptions spelled out, milestones you can see, and a demo at every step.

You own everything

Code, tests, documentation and runbooks live in your repository from day one.
