W.Media Ticketing System

Overview

Built a comprehensive ticketing system for W.Media that manages event registration, seat allocation, payment processing, and attendee check-in for large-scale technology conferences across Asia Pacific.

Problem

W.Media needed a scalable solution to handle ticket sales for multiple simultaneous events, supporting thousands of concurrent users during peak registration periods.

Solution

Designed and implemented a microservices-based ticketing platform with real-time seat availability, queue management, and integrated payment gateways.

Architecture

Microservices architecture with Laravel backend, Vue.js frontend, Redis for caching and queue management, PostgreSQL for data persistence, and AWS infrastructure.

Challenges

• Handling race conditions during concurrent seat selection
• Implementing real-time availability updates across multiple browser sessions
• Scaling the payment processing pipeline for peak loads

Key Learnings

• Optimistic locking patterns for concurrent resource allocation
• Event-driven architecture for real-time updates
• Load testing and capacity planning strategies
