APIs that other developers enjoy using
REST and GraphQL APIs designed, versioned and documented properly — plus the integration work that gets your existing systems talking to each other reliably.
- Node.js
- NestJS
- GraphQL
- OpenAPI
- Kong
- Redis
- RabbitMQ
- Postman
What you get
- API design and resource modelling
- OpenAPI or GraphQL schema definition
- Implementation with automated tests
- Authentication and rate limiting
- Interactive developer documentation
- Sandbox environment for consumers
- Monitoring, logging and alerting
The approach
How we think about api development
An API is a product with its own users. We design them for the developers who will consume them: predictable resources, honest error messages, sensible pagination, and documentation that is generated from the same source as the code.
On the integration side, the difficulty is rarely the happy path. It is timeouts, duplicate deliveries, partial failures and rate limits. We build for those with idempotency keys, retry policies with backoff, dead-letter queues and reconciliation jobs.
Everything is monitored. When a third party has an outage — and they will — you find out from an alert rather than from a customer.
Included as standard
The details that decide whether it works
REST and GraphQL
Whichever suits the consumer, designed to a consistent standard.
OpenAPI documentation
Interactive docs generated from the schema and always current.
Authentication done right
OAuth 2.0, API keys, JWT, scoped permissions and key rotation.
Rate limiting and quotas
Per-client throttling that protects the platform under load.
Webhooks with guarantees
Signed payloads, retries with backoff and delivery logs.
Versioning strategy
Additive changes and deprecation windows so nothing breaks silently.
Common questions
API Development, answered
Yes. We audit the existing endpoints, produce an OpenAPI specification, publish interactive docs and flag the inconsistencies worth fixing before external developers meet them.
We regularly wrap SOAP and other legacy interfaces behind a clean modern API so new development is not held back by the old contract.
We version explicitly, keep the previous version running through an agreed deprecation window, and notify consumers with a migration guide.
