API Development

I build APIs that are fast, secure, and well-documented. RESTful endpoints with proper authentication, input validation, rate limiting, and interactive documentation that other developers actually enjoy using.

What makes a great API

A great API isn't just functional. It's intuitive, consistent, and well-documented. Developers working with your API should be able to understand it in minutes, not hours. I follow RESTful conventions and provide comprehensive documentation.

Security is non-negotiable. Every API I build includes proper authentication (JWT, OAuth), input validation, rate limiting, and error handling. No SQL injection, no unauthorized access, no silent failures.

Performance matters at the API level too. I implement efficient database queries, response caching, pagination, and compression to ensure your API responds quickly even under heavy load.

APIs I've built

From user authentication systems and payment processing to AI model integrations and real-time data streams, I've built APIs across a wide range of use cases and industries.

I design APIs with versioning, backward compatibility, and scalability in mind. When your user base grows 10x, your API shouldn't be the bottleneck.

Every API comes with interactive documentation so your team or third-party developers can integrate with confidence. Clear examples, error codes, and response schemas included.
