Solution
APIs Built for Production — Not Just the Happy Path
RESTful and GraphQL APIs with auth, rate limiting, and documentation built in.
Backend API development covering authentication, rate limiting, versioning, documentation, and the integrations your product depends on. Built with TypeScript, Node.js, and your chosen database.
The problem
What I address
- Frontend blocked because the API keeps changing without communication
- No rate limiting or authentication on customer-facing API endpoints
- Missing documentation that makes every integration a support ticket
- N+1 query problems and unoptimized endpoints causing database load at scale
Output
What you get
- 1OpenAPI spec first — documentation that matches the actual implementation
- 2Authentication with JWT and API key support
- 3Rate limiting per plan tier with 429 responses and backoff headers
- 4Versioning strategy that allows breaking changes without breaking clients
- 5Webhook support with retry logic and delivery logs
How it works
The process
API design
Design the API contract first — endpoints, request/response shapes, error codes.
Auth & security
Implement authentication, authorization, and rate limiting.
Core endpoints
Build each endpoint with validation, error handling, and logging.
Testing & docs
Integration tests for every endpoint and up-to-date OpenAPI documentation.
Deployment
Deploy with monitoring, alerting, and a runbook for on-call.

FAQ
Common questions
REST or GraphQL?+
REST for most cases — predictable, cacheable, and familiar to any consumer. GraphQL when you have a complex graph of related resources and multiple clients with different data needs.
Do you build SDKs too?+
Yes. I can generate or hand-write SDK clients in TypeScript (Node/browser) and Python for your API.
