Clean, documented APIs that are a pleasure to integrate.
A poorly designed API is technical debt that multiplies across every client that uses it. I design APIs that are predictable, secure, well-documented, and easy to integrate with — because the people consuming your API are customers too.
Everything in scope
- REST & GraphQL API design
- Authentication (JWT / OAuth)
- Third-party API integrations
- API documentation (OpenAPI)
- Rate limiting & security
Who this is for
- Products building mobile or third-party integrations
- Businesses opening their platform to external developers
- Teams that need a reliable backend API layer
- Apps separating frontend from backend
The process
Design
Endpoint structure, auth pattern, versioning strategy, and error format — agreed before implementation.
Build
Implementation with proper input validation, authentication, and rate limiting.
Document
OpenAPI (Swagger) documentation with examples for every endpoint.
Test
Integration tests for all endpoints including edge cases and error paths.

Common questions
REST or GraphQL?
REST for most APIs — simpler, cacheable, better understood. GraphQL when clients need flexible queries and you have complex, interconnected data. I'll recommend based on your use case.
How do you handle API authentication?
JWT for stateless APIs, API keys for third-party integrations, OAuth 2.0 for user-facing flows. I choose based on who is consuming the API.
Can you build a public API for third-party developers?
Yes — including API key management, rate limiting, usage tracking, and developer documentation pages.
