Over a two-month period, contributed to the MrCin23/IO repository by building a robust account-centric registration and authentication system, focusing on secure onboarding and scalable user management. Leveraged Java, Spring Boot, and React to implement JWT-based authentication, role-based access control, and comprehensive user management features, including password reset and last login tracking. Enhanced both backend and frontend with improved input validation, error handling, and internationalization support, while aligning database schemas and codebase naming conventions for maintainability. Addressed critical bugs in registration and user experience, resulting in a more reliable authentication flow and clearer navigation for end users across the application.
