At American Express Global Business Travel, I re-engineered refund processing for agent-assisted cancellations, reducing end-to-end errors by 8%. I also built an AWS Kinesis pipeline processing about 100K booking events each month.
I've led zero-downtime legacy-service decommissioning, cutting infrastructure costs by about 15%, and introduced hexagonal architecture that reduced production incidents from roughly 10 to 1–2. My backend work improves observability, API documentation, and reliability across distributed microservices.
Previously at GE HealthCare and Western Digital, I built an LLM-powered clinical application adopted by 100 clinicians, production imaging tools, and microservices. I also migrated a .NET monolith into three microservices and built platforms for hardware-log analysis and firmware anomaly alerting.
