Scaling cross-border payments with a sub-50ms event-driven transaction ledger.
Engineered a high-throughput microservices architecture processing over $120M in monthly cross-border transactions with zero ledger discrepancies.
System bottlenecks & technical limits
StrataPay was experiencing 4-second transaction bottlenecks and nightly database locking issues during peak settlement windows, threatening their compliance SLA with international banking partners.
Bespoke architecture & deployment
SOLVIXBIT re-architected their core ledger from a monolithic SQL database into an event-driven Go and Kafka microservice cluster hosted on AWS ECS, with distributed Redis caching and automated reconciliation workers.
How the system was engineered
Event-driven Kafka messaging pipeline with at-least-once delivery semantics
High-performance Go microservices delivering sub-50ms REST and gRPC endpoints
Multi-region PostgreSQL read replicas with automatic failover and point-in-time recovery
Automated reconciliation bot matching 50,000+ bank ledger entries every 60 seconds
SOLVIXBIT did not just write code; they completely re-engineered our core payment infrastructure. Our settlement speed increased tenfold, and our enterprise bank partners are thrilled.
