At Amazon, I lead the design of high-volume transaction-processing services for Amazon Pay, building Java and Spring microservices for new financial features. I own data models, API contracts, deployment pipelines, and integration patterns across payment services and external processors.
Previously at Amazon Health Services and e-Commerce Foundation, I modernized patient-data ingestion into a Kafka-based architecture, reducing daily batch latency from roughly six hours to under 45 minutes. I've also built consent-management APIs, de-identification services, clinical operations tools, and checkout-orchestrator migrations with zero customer-visible issues.
I began building reliable Java mission-planning software for Lockheed Martin satellite ground systems, where I improved legacy modules, migrated data ingestion to Hibernate and Spring Data JPA, and resolved critical production issues for satellite operators.
