Custom API Development
Production-grade APIs built with NestJS and TypeScript.
I design and build RESTful APIs with NestJS, TypeScript, and PostgreSQL. Authentication, authorization, rate limiting, documentation (Swagger), and comprehensive test coverage — all following production best practices.

Deploy to production, set up monitoring, and deliver comprehensive API documentation.
Frequently asked questions
Can you extend an existing API?
Yes — I can add endpoints, modules, or features to existing NestJS or Express.js applications. I will start with a code review to understand the existing architecture.
Do you build GraphQL APIs?
I primarily work with REST APIs for their simplicity and tooling ecosystem. I can build GraphQL APIs when the use case warrants it (complex relational queries, mobile apps with variable data needs).
