High-frequency trading system for a financial institution with millisecond-level order processing
Project Overview
Built a next-generation trading core system for a leading fintech company, meeting extreme performance requirements and strict compliance standards. The system design goal was to achieve microsecond-level latency, hundreds of thousands of transactions per second, while ensuring zero data loss and high system availability.
Challenge
Extremely low-latency order processing while ensuring data consistency and high availability. Financial regulations were strict, with data security and audit compliance as hard requirements.
Solution
LMAX architecture pattern with in-memory databases and lock-free queues for microsecond-level order matching. Designed multi-active architecture for high availability, with complete audit logging and risk control systems.
Results
Order processing latency reduced to under 100 microseconds, system throughput of 100,000 transactions per second, zero data loss.
