How we work

Four things that hold true on every engagement, whether it runs six weeks or six months.

You talk to the engineers

No account managers, no handoff to juniors after the pitch. The people who scope your project are the people who write it.

Scoped before it starts

Every engagement is defined against a signed SOW — deliverables, timeline, and price agreed up front. No open-ended hourly drift.

You own all of it

Source, infrastructure, accounts, and deployment keys are yours from day one. Nothing sits behind a licence you have to keep paying us for.

We stay past launch

Shipping is the middle of the job, not the end. Monitoring, maintenance, and the next iteration are part of how we plan the work.
