API Development & System Integration
APIs, microservices and integrations that other teams can rely on: designed contract-first, tested automatically and documented properly.
Your APIs are a product. We build them like one.
An API is a promise to every system and team that depends on it. Break that promise and the failures show up somewhere else, often in production, often at the worst time.
We design and build REST APIs, backend services and integrations between your systems and the platforms you rely on: payments, CRMs, identity providers, data feeds and internal services.
Every API we build ships with automated contract and integration tests, clear documentation and versioning that lets it change without breaking its consumers.
What we build
Services and integrations that hold up
REST API design & build
Contract-first APIs with OpenAPI specifications, consistent conventions and sensible versioning.
Microservices & backend services
Well-bounded services in Node and TypeScript, built to be deployed, scaled and tested independently.
Third-party & system integration
Connecting your platforms to payment providers, CRMs, identity services and partner systems, with retries, monitoring and clear failure handling.
Contract & integration testing
Automated tests that catch breaking changes before they reach consumers, run on every merge.
How we work
Contract first, then code
- 01
Agree the contract
Define endpoints, payloads and error behaviour with the teams who will consume the API before building it.
- 02
Build behind tests
Implement against the contract with automated tests proving it holds, from day one.
- 03
Integrate safely
Connect to real systems in stages, with sandbox testing, monitoring and rollback plans.
- 04
Document and evolve
Publish clear documentation and version changes so consumers are never surprised.

FAQs
Common questions
Can you integrate with our existing systems and suppliers?
Yes. A large part of our API work is integration: connecting your platforms to each other and to third-party services, with proper error handling, monitoring and tests so the integration keeps working when either side changes.
How do you stop API changes breaking other teams?
We design the contract first, version it, and run automated contract and integration tests on every change. Breaking changes are caught in the pipeline, not reported by a consumer in production.
Do you also test APIs built by other teams?
Yes. Our API testing service covers functional, contract, security-focused and performance testing of APIs we didn’t build.
