Event Ticket Booking System with QR Code-Based Entry Validation
Problem Statement
An event management company wanted to digitize its ticket booking and entry process. Their traditional system relied on paper tickets and manual verification, which caused long queues, ticket fraud, and poor user experience. They required a full-stack web application that could handle online bookings and support QR code-based entry validation at the event venue.

Challenge
Scalability: The system had to manage thousands of concurrent ticket bookings during high-demand events.
Security: Preventing ticket duplication, forgery, and unauthorized access was critical.
Real-Time Validation: Entry staff needed to scan and validate tickets instantly with zero delays.
Role-Based Access: Different dashboards and permissions for admins, organizers, and attendees were required.
Cross-Platform Compatibility: Booking and scanning needed to work smoothly on mobile, tablet, and desktop devices.
Solution Provided
A robust full-stack event ticketing platform was developed using React (frontend), Node.js and Express (backend), and MongoDB (database), with QR code generation and scanning features.
Key Features:
Online ticket booking with dynamic pricing and seat selection.
Secure payment integration using Stripe.
QR code generation for each ticket at the time of booking.
QR code scanning via mobile devices by event staff.
