FinScale Global: Go Microservices Handling 8x Volume
Re-architecting legacy transaction pipelines into high-throughput Go microservices with zero downtime during migration.
The Challenge
FinScale Global experienced database lock bottlenecks and API timeouts during peak trading hours. Their monolithic Node.js backend couldn't scale horizontally without expensive cloud resources.
The Solution & Engineering
We decomposed the monolith into compiled Go microservices communicating via gRPC and Redis streams, partitioning PostgreSQL database reads into replica pools.
