Yehor Kovalenko developed a robust user management and authentication system for the EmergencyProject repository, focusing on secure onboarding, role-based access, and seamless frontend-backend integration. He implemented JWT-based authentication with http-only cookies, refresh tokens, and extended token payloads to support scalable access control. Using Java, Spring Boot, and Vue.js, Yehor designed a component-based architecture with DTO-driven data flows, secure password handling, and multilingual support. His work included database schema alignment, admin role integration, and comprehensive test data seeding, resulting in a maintainable, secure foundation for user registration and authorization. The engineering demonstrated depth in both backend and frontend domains.

January 2025: Delivered end-to-end authentication and admin capabilities, strengthened data integrity, and completed frontend-backend integration to enable secure, scalable user management and role-based access across the EmergencyProject suite.
