No More Waiting in Line: How I Built a Web-Based Canteen Queue Management System with Flask and MongoDB
Lakshmi Saravanan developed a web-based Canteen Queue Management System to alleviate long wait times for college students. The system allows students to place orders online and track their queue position, while staff can manage orders efficiently through an admin dashboard. This project aims to enhance the overall canteen experience by integrating technology into the ordering process.
- ▪The system enables students to order food online and receive real-time notifications when their order is ready.
- ▪Canteen staff can manage orders through a user-friendly admin dashboard designed for efficiency.
- ▪The project emphasizes a design-first approach, prioritizing user experience for both students and staff.
