Global Payments Architecture Modernization
Challenge: Legacy monolithic server pipelines experienced database lockups and payment timeouts during high-traffic enterprise shopping events.
Strategy: Overhauled the transaction routing by decoupling ledger entries and migrating to an event-driven cluster structure.
Solution: Engineered distributed Node.js microservices coordinated via Apache Kafka, Docker, and autoscaling AWS Kubernetes clusters.
Results: Achieved zero transaction drop rates, a guaranteed 99.999% system uptime SLA, and handled transaction processing spikes exceeding 10,000 requests per second.
