Contributed to the KMUTT-CampusLink suite by delivering six new features and resolving one bug across both client and server repositories. Focused on enhancing student and instructor workflows, this work included building richer course data views, streamlined assignment management, and robust end-to-end submission flows. Leveraged React and JavaScript for frontend development, implementing reusable components and hooks, while backend improvements used Node.js, Express.js, and Prisma ORM to support new REST API endpoints and SQL refactoring. Integrated MinIO for file uploads, enabling secure assignment storage and retrieval. These enhancements improved system scalability, user experience, and maintainability across the platform’s codebase.
