Worked on the ucsb-cs156/proj-frontiers and related repositories to deliver secure admin governance features and frontend admin email management. Developed backend APIs for admin management with robust role-based access control using Java and Spring Boot, including startup logic to preload administrator emails from configuration. Enhanced the React-based RoleEmailTable component for managing admin emails, simplifying its interface and expanding test coverage with Jest and React Testing Library. Focused on maintainability by cleaning up tests, improving formatting, and integrating TestPropertySource. The work emphasized automated testing and component refactoring, supporting developer velocity and reducing onboarding risk while ensuring reliable admin account management.
