I build reliable, maintainable backend systems and REST APIs for SaaS products and web applications.

Whether you need a new backend, additional API endpoints, integrations, or improvements to an existing service, I can take the work from technical design through implementation and testing.

What I can help with: • Node.js / TypeScript backend development • NestJS, Express.js, and Hono • REST API design and implementation • PostgreSQL database design • Query optimization and indexing • Authentication and authorization • Third-party API integrations • Redis and event-driven systems • Testing, observability, and deployment

I can also work directly within an existing backend codebase and improve or extend it without requiring a complete rewrite.
