Developed a robust user management and authentication system for the EmergencyProject repositories, delivering secure onboarding, role-based access, and seamless frontend-backend integration. Leveraged Java, Spring Boot, and Vue.js to implement JWT-based authentication with http-only cookies, refresh tokens, and granular access control for roles such as Admin, Giver, NGO, Official, and Volunteer. Designed and integrated Data Transfer Objects (DTOs), entity inheritance, and secure password handling using BCrypt. Enhanced data integrity through database schema alignment and test data seeding, while supporting multilingual interfaces and localStorage-backed session management. Addressed merge conflicts, improved logging, and ensured maintainable, scalable architecture across backend and frontend.
