API Development

Secure, well-documented REST and GraphQL APIs that let your systems talk to each other and to the partners you integrate with.

APIs are how your systems stop being islands. Done well, they are boring infrastructure that just works. Done badly, they become the most fragile part of your stack.

We build REST and GraphQL APIs that are documented, versioned and secured properly — whether you are exposing data to a mobile app, connecting to a partner system, or splitting a monolith into services.

What good looks like

Predictable resource naming, sensible status codes, authentication that suits the consumer, rate limiting, and documentation another developer can build against without calling you.

We also handle the unglamorous parts: pagination, error formats, idempotency for operations that must not run twice, and a versioning strategy so future changes do not break existing clients.

Yes. We take on extending, documenting and stabilising APIs we did not write, including cases where the original developers are no longer available.
