How LOGIC NOSH re-architected a legacy monolithic payment processor into decoupled Go microservices, eliminating database lock contention and unlocking 10x throughput.
As daily transaction volume tripled within six months, the single monolithic PostgreSQL database began experiencing severe row-level locking during batch reconciliations. Requests queued up, causing timeout cascades that propagated to client mobile apps and partner banking endpoints.
Engineers were routinely paged during market opening hours. Row-level table locks froze clearing pipelines, forcing manual database interventions and customer support escalations.
A 12-week phased migration utilizing the Strangler Fig pattern. In Weeks 1-4, an intelligent API gateway was deployed with parallel shadow traffic. In Weeks 5-8, high-frequency clearing was shifted to Go microservices. In Weeks 9-12, the legacy monolith was completely decoupled.
Adopted Go for the clearing service to achieve predictable garbage collection and native concurrent goroutines.
Implemented Kafka message queues to decouple synchronous transaction intake from asynchronous ledger persistence.
Enforced strict gRPC contracts with Protocol Buffers between internal backend services.
We designed and engineered high-density operator dashboards, mobile workflows, and responsive telemetry consoles.
