Ola Bryja developed a robust authentication and user management system for the MrCin23/IO repository, focusing on account-centric registration, secure onboarding, and role-based access control. Leveraging Java, Spring Boot, and React, Ola restructured the backend with a new Account entity, implemented JWT-based authentication, and enforced input validation and error handling to improve reliability. The frontend was enhanced with Bootstrap and internationalization, introducing private routes and user-friendly navigation. Ola addressed stability issues in registration and login flows, fixed user experience bugs, and standardized database schema naming. This work delivered a scalable, maintainable foundation for secure user management and access control.
