An API is a contract, and contracts outlive the code behind them. I design them to be versioned, documented, and boring to consume — so the teams building against yours never have to guess.
What I Build
- REST and GraphQL services — built on Node.js with Express, Nest.JS, Hono, or Bun, chosen to fit your runtime and team rather than fashion.
- Type-safe data layers — Drizzle or TypeORM over PostgreSQL and MySQL, with migrations that run cleanly in CI.
- Authentication and authorisation — OAuth 2.0, JWT rotation, API keys, rate limiting, and per-tenant scoping.
- Caching and throughput — Redis layers, query optimisation, and pagination strategies that hold up under real traffic.
- Third-party integrations — payment providers, CRMs, and legacy SOAP or XML endpoints wrapped behind a clean internal interface.
Built To Be Consumed
Every endpoint ships with an OpenAPI or GraphQL schema, generated client types, and contract tests. Breaking changes go through explicit versioning, never a silent deploy.
Typical Engagements
- Standing up a new backend for a web or mobile product from scratch.
- Extracting an API layer out of a legacy monolith without a big-bang rewrite.
- Hardening and documenting an existing API before opening it to partners.
