Jg Bocobo developed a user notification system for the CMSC128 repository, focusing on backend functionality using Node.js, Express.js, and RESTful API design. The system introduced an API endpoint and backend controller that allowed authenticated users to fetch their unread notifications and mark them as read, leveraging authentication context to ensure secure, per-user data access. By decoupling notification data from the user interface, Jg laid the foundation for future frontend integration and analytics. The work emphasized clean code practices and stability, addressing the need for timely, persisted notifications while reducing manual checks and improving overall user engagement within the application.
