Jay Joo

Over a two-month period, contributed to the ucsb-cs156-s25/team02-s25-12 repository by building a secure, full-stack management system for UCSB Dining Commons Menu Items. Developed a RESTful backend API with Spring Boot and Java, implementing CRUD operations with role-based access control and comprehensive unit testing using JUnit and Mockito. On the frontend, created React-based UI components, including index, create, and edit pages, with robust form handling and Storybook-driven development. Enhanced reliability through integration and end-to-end testing with Playwright and Jest, and addressed test stability and formatting issues. These efforts established a scalable, production-ready foundation for menu item management.
