Worked on the ucsb-cs156/proj-courses repository to deliver two impactful features focused on scalability and user experience. Enhanced the H2 database configuration to support concurrent multi-user access, tuning properties to enable simultaneous connections and improve system scalability for coursework management. Refactored the SectionsTable component using React and JavaScript, integrating backend mutation logic for clearer error handling and success messaging, which improved both user feedback and maintainability. Also addressed code quality by removing unnecessary ESLint exceptions as part of the refactor. Leveraged skills in front end development, Java, and database management to align technical solutions with business requirements.
