Backend and API development
Most teams that call us have a working product and a backend that is now the reason they cannot ship. It was written fast, by someone who has left, against requirements that have since changed twice. The question is never "can you write an API" — it is whether you can work inside that and leave it better without a rewrite nobody funded.
Four ways this arrives.
We read the code, write down what it does versus what everyone believes it does, and give you the list of the five things most likely to page someone at night. Then we fix those first.
Usually queries, not architecture. We profile under real traffic, fix the plans and the indexes, and only then discuss whether anything needs splitting apart.
A mobile client, a partner integration, a public API. We design the contract first, version it properly, and write the docs your consumers will read.
Jobs that silently vanish, retries that duplicate charges, a queue nobody monitors. We make it idempotent, observable, and boring.
A moderated messaging backend where sends acknowledge in-band and the review runs behind them.
Read the write-up →Asked on nearly every call.
Can you work in our existing codebase?+
Yes, and it is most of what we do. We do not require a rewrite as a condition of working with you. If we think a rewrite is genuinely the right call we will say so, with the reasoning and the cost, and you can decide.
What if the backend is in a language you do not list?+
Then we will tell you. We are useful in Node, Python and TypeScript. We can read Go and PHP well enough to migrate off them. We would not take a Rust or Elixir project and learn it on your budget.
Do you write tests?+
For anything with money, permissions or data loss in it, yes. We do not chase a coverage number. We will tell you which parts are covered and which are not in the handover notes.
Who owns the code?+
You do, from the first commit. Repositories live in your organisation. If we set them up, we transfer them before the first invoice.
What happens when the engagement ends?+
You get runbooks, architecture notes and a recorded walkthrough. We stay available for questions for a month at no cost, because a handover that needs us on retainer is not a handover.
