API & Backend Engineering
Secure, well-documented APIs that scale.
An API is a contract. We design ours to be predictable, versioned, and documented so the teams and clients that depend on them are never guessing. Under the hood that means clear service boundaries, sensible error handling, and tests that pin the behaviour down.
Whether it is a REST or GraphQL surface, a webhook system, or the backend for a mobile app, we build it to handle real traffic and to be observable when something goes wrong.
What you get
- REST or GraphQL API design and implementation
- Authentication, rate limiting and input validation
- OpenAPI documentation
- Background jobs and queue processing
- Integration tests and monitoring
Common questions
REST or GraphQL?
It depends on the clients. We help you choose based on how the API will be consumed rather than on fashion, and we can build either.
Can you document an existing API?
Yes. We can add OpenAPI specs, validation and tests to an undocumented service so the next team can work against it safely.
How do you secure the API?
Authentication on every route, strict input validation, rate limiting, and least-privilege access to data. Security is built in, not bolted on.
Can you scale an API that is hitting its limits?
Yes. We profile where the time and load actually go, add caching and queues where they help, and optimise the database before reaching for bigger, pricier infrastructure.
Do you handle versioning and backwards compatibility?
Yes. We version the API and treat the contract as something clients depend on, so upgrades do not break the teams building against you.
