Summary

QUEUE! is a comprehensive healthcare queue management system designed to optimize patient flow in clinics and hospitals. It features a touch-friendly kiosk for patient check-in, an advanced operator console for triage and queue control, and dynamic TV displays for waiting rooms.

The system handles the full lifecycle of a patient visit: from self-service ticket issuance with ID recognition to priority-based calling and analytical reporting. It is designed as a modular SaaS platform capable of running in hybrid environments.

Engineering Challenges

Synchronization of real-time state between the kiosk, operator panel, and TV displays using Server-Sent Events (SSE) proved challenging under high concurrency. We solved this by implementing a robust event buffering system in the .NET backend to ensure no updates were lost during connection flickers.
