Cloud-Based Restaurant POS & IoT Attendance
This system is actively deployed and used daily in restaurant operations. Built with Flutter for the mobile interface and Firebase Firestore for real-time sync, it supports four roles: admin, waiter, kitchen, and receptionist. The kitchen display system divides orders into three sections (soup, drinks, main dishes) so staff can track and complete each item. The IoT attendance module uses ESP32 with Firebase RTDB to automate staff check-in/check-out with centralized cloud updates.
