Event-Driven Microservices with Real-Time Data Synchronization

Architected a real-time booking system using event-driven microservices to handle high-concurrency booking operations with sub-second latency requirements.

Challenges

  • Sub-second real-time synchronization across distributed services
  • High-concurrency booking operations (10,000+ concurrent requests)
  • Unified payment gateway abstraction with failover

Solutions

  • Implemented event-driven architecture with Apache Kafka for service decoupling
  • Engineered WebSocket infrastructure with Redis pub/sub for instant updates
  • Created unified payment processing layer with circuit breakers
