QbuddyX

🚀 QBuddyX – Project Write-Up 🌟 Inspiration

Long queues in hospitals, colleges, government offices, canteens, and service centers waste hours of people’s time. Elderly and disabled people suffer the most.

We wanted to create a solution where people never have to stand in a physical line again. A system where:

Users join queues from their phone

Organizations manage queues with one click

AI takes care of waiting, alerts, predictions, and communication

This vision gave birth to QBuddyX — Your Virtual Queue Partner.

⚡ What it does

QBuddyX replaces physical lines with a smart, AI-powered digital queue system.

Users can:

Scan a QR code

Organizations can:

Everything is real-time with WebSockets, and fully multi-language (8 languages).
