The service in 4 parts
01 · Who it’s for
A company that knows what it is building and needs senior developers who work on both the frontend and the backend. Usually the product is already live with its own team, and it has to keep running while we change it.
02 · What we’ve built
- A marketplace codebase shared by five kinds of user, with permissions set by type and role. The API repeats every check the interface makes.Case study 08 →
- An ERP that runs alongside SAP for a construction company: 150,000 items in 15 warehouses, and crews planned by trade across several countries.Case study 16 →
- An analytics layer that takes two million writes a day, updates the customer’s dashboard live and returns a year of history in under a second.Case study 05 →
- A live marketplace moved from PHP to Node.js with no outage. Lighthouse rose from 60 to above 90 once its public site moved to Next.js.Case study 04 →
03 · How we work
01 · DECISIONSSchema changes and API contracts are written down with the reason behind them. Whoever works on the frontend or the backend later can see why, and reopen the decision without starting the argument over.
02 · CODE RULESThey run in a pre-commit hook and again in CI, on the frontend and the backend alike. On the marketplace they included a typed request and response for every API call.

Yes. Additional developers join your team full-time, as described on the dedicated developer page.
You do. We set out three options, each with its price and what would have to be true in two years for it to pay off, and explain which one we recommend and why.
