Sub-10ms Core Banking Ledger Migration
The Challenge
Monolithic database bottlenecks during peak market hours resulted in ledger sync delays of up to 4.2 seconds, causing intermittent timeout cascades and customer-facing balance discrepancies during high-volume trading surges.
The Architecture Solution
Decoupled the monolithic database into an event-driven distributed microservice mesh using Go and Apache Kafka. Implemented distributed transactional consensus on multi-region CockroachDB with Redis Enterprise in-memory state caching and automated circuit breakers.
