Service

API and Backend Engineering

Secure, well-documented APIs and backend services that connect applications, partners and data.

The business problem

Systems that cannot talk to each other create duplicate data and fragile manual workarounds. Poorly designed APIs become difficult to change and hard to secure.

The outcome

A clean integration layer with stable contracts, proper authentication and the performance to support growth.

What we can build

  • REST and GraphQL APIs
  • Third-party and partner integrations
  • Event-driven and queue-based services
  • Authentication, authorisation and API key management
  • Performance optimisation of existing backends

Typical deliverables

  • API design and OpenAPI specification
  • Implemented services with automated tests
  • Rate limiting, logging and error handling
  • Developer documentation
  • Load testing and performance report

Relevant technologies

We choose tools to fit your requirements and existing stack. Commonly used:

  • Node.js
  • Python
  • Go
  • PostgreSQL
  • Redis
  • OpenAPI
  • RabbitMQ

FAQ

Common questions

Relevant industry solutions

Can you document and stabilise an existing API?

Yes. We can audit an existing backend, produce documentation, add tests and fix the highest-risk issues before extending it.
