Architected a real-time transaction compliance engine processing 50,000+ transactions per second with sub-10ms latency for regulatory screening across 40+ jurisdictions.
The client operated across multiple regulatory regimes with conflicting requirements. Their existing batch-processing compliance system introduced 4-hour settlement delays, creating counterparty risk and regulatory exposure. They needed a real-time solution that could apply jurisdiction-specific rules at transaction velocity without sacrificing audit trail completeness.
We designed an event-driven compliance engine using Go microservices with a Redis Streams message backbone. Each transaction triggers parallel rule evaluation pipelines—sanctions screening, AML pattern detection, jurisdiction-specific regulatory checks—with results aggregated by a deterministic scoring engine. The architecture uses CQRS for separating read/write paths, ensuring compliance queries never impact transaction processing latency.
