API & Backend Development

Well-designed APIs, services and data layers that keep products fast, secure and easy to extend.

Overview

Robust backends and APIs for modern products.

A product is only as reliable as its backend. I design REST and real-time APIs, microservices, data models and background processing with testing, documentation and observability — and integrate AI services where they add value.

Use cases

  • Mobile app backends
  • SaaS platforms
  • AI / document processing services
  • Integration hubs

Problems solved

  • Backends that slow down as usage grows
  • Undocumented APIs nobody wants to touch
  • Security gaps in auth and data access
  • Monoliths that block independent deployment

What's included

  • REST and WebSocket API design
  • Microservice architecture
  • Auth, RBAC and security hardening
  • Database design and optimisation
  • Background jobs and queues
  • Testing, docs and CI/CD

Deliverables

  • API specification
  • Backend services
  • Automated tests
  • API documentation
  • Containerised deployment
