01 OVERVIEW
The School Visitor Queue Management System replaces traditional paper-based visitor registration with a fully digital workflow. Visitors can scan a QR code, check in, receive queue tokens, and monitor their status in real time. Staff manage multiple service counters through dedicated dashboards, while administrators monitor operations, generate reports, and analyze queue performance. The system synchronizes every connected screen instantly using PostgreSQL-driven event processing and native WebSockets.
02 CHALLENGE
Concurrent Queue Processing
Multiple service counters needed to process visitors simultaneously without race conditions or inconsistent queue states.
Real-Time Synchronization
Every visitor status update had to instantly synchronize across kiosks, counter dashboards, lobby displays, and administrative panels.
Complex Queue Logic
Building a reliable FIFO queue engine with transactional consistency, analytics, and audit tracking entirely within PostgreSQL.
Multi-Device Experience
Providing a seamless experience across visitor kiosks, operator dashboards, large display screens, and mobile notifications.
03 SOLUTION
Engineered a real-time queue management platform using PostgreSQL stored procedures, triggers, row-level locking, native WebSockets, and role-based dashboards. The system delivers instant synchronization, reliable queue processing, automated notifications, and comprehensive operational analytics.
