RestroBook: Next-Generation Restaurant Reservation System

High-volume dining establishments face persistent revenue loss due to last-minute no-shows, fragmented phone reservations, and seat allocation deadlocks during peak service windows. Concurrently booking patrons often triggered table double-booking, while floor managers lacked an automated mechanism to release abandoned tables in real time.

RestroBook was developed using a dual-portal architecture separating the diner booking experience from restaurant floor management. The frontend is built with React.js, Vite, and Tailwind CSS, providing sub-second page transitions and interactive slot selection grids. The backend utilizes Node.js, Express.js, and MongoDB with Mongoose object modeling. A custom dynamic time-slot scheduling algorithm computes table availability against party sizes and reservation durations. Automated Node-cron background workers execute every 60 seconds to detect unconfirmed reservations, transition lapsed bookings to available inventory, and notify waitlisted patrons. Secure JWT role middleware strictly isolates administrative table configuration from public customer reservations.

The automated reservation engine eliminated double-booking errors entirely and reduced table vacancy between dining shifts by 28%. Background cron daemons reduced manual front-desk attendance checks by 90%, while the responsive booking portal delivered sub-40ms slot availability lookups across peak Friday and Saturday dinner service windows.
