Backend Developer Intern

Alfa Information Technologies

Developed and tested 10+ RESTful APIs using Core Java, Spring Framework, Spring Boot, and Node.js/Express.js, applying Controller–Service–Repository architecture to keep software modules, CRUD logic, and database operations modular and maintainable. Implemented JWT-based authentication and authorization with input validation and exception handling, securing protected API endpoints and applying clean, maintainable coding practices. Integrated MySQL/JPA and MongoDB for backend data operations, using Postman to test, debug, and troubleshoot REST APIs across service and database layers before handoff.
