Developed an admin-facing Courses index page for the ucsb-cs156/proj-frontiers repository, enabling administrators to view and manage course data directly through the user interface. The implementation featured a React-based CoursesTable component that dynamically fetched data from the backend, ensuring up-to-date information was always displayed. Navigation was updated to provide seamless access to the new page, integrating it smoothly into the existing admin workflow. Comprehensive tests were written to validate rendering, data fetching, and navigation logic, emphasizing reliability and maintainability. The work leveraged frontend development skills with a focus on React, JavaScript, and HTML, delivering a robust and testable feature.
