I build secure, reliable, and maintainable REST APIs and backend functionality for web applications.

I can help with: • REST API development • Backend business logic • Authentication and authorization • PostgreSQL/MySQL database integration • API validation and error handling • Third-party API integrations • SQL query optimization • Existing backend fixes and improvements • Dockerization and deployment support

I work with Node.js/Express, FastAPI, and Spring Boot depending on your existing stack and project requirements.

I focus on clean architecture, maintainable code, security, testing, and reliable API design.

Please message me with your requirements and existing tech stack before starting so I can confirm the scope.
