About This Project

Developing a matching engine in Go for low-latency order processing, using in-memory data structures for order books, PostgreSQL for persistent storage, Redis for caching, and WebSockets for real-time price and order updates.

Order matching engine processes trades in-memory, PostgreSQL stores orders and trade history, Redis caches market data, WebSocket server broadcasts real-time updates to connected clients.

Challenges

  • Implementing a fair and efficient order matching algorithm
  • Ensuring data consistency between in-memory and persistent storage
  • Handling high-frequency trading scenarios with low latency
  • Managing concurrent order submissions safely

Key Learnings

  • Financial trading systems architecture
  • Low-latency system design in Go
  • Order book data structure optimization
  • Real-time data streaming with WebSockets
