Iker Barranco developed a secure, full-stack user authentication and item management system for the BSPQ24-25/BSPQ25-E3 repository over three months. He implemented end-to-end JWT-based authentication and authorization using Java, Spring Boot, and React, integrating BCrypt for secure password storage and enforcing robust access control across frontend and backend. His work included expanding user registration and profile features, enhancing item and loan management workflows, and introducing internationalization and performance monitoring. By focusing on privacy, reliability, and maintainability, Iker delivered a scalable foundation for future role-based access and multilingual support, demonstrating depth in API development, security, and test-driven engineering practices.
