I've built high-throughput Java microservices for Kaiser Permanente and FedEx through Accenture, supporting enterprise healthcare and logistics platforms.
For Kaiser Permanente, I engineered role-based authentication serving three applications, built a real-time membership data-comparison portal, and delivered a self-service error-reprocessing console that reduced developer dependency by about 60%. I also led the zero-downtime Azure migration of three Spring Boot microservices and resolved more than 15 security vulnerabilities.
For FedEx, I developed transaction services for checkout and refund workflows across in-store and online retail channels. I resolved 30+ post-migration data-integrity defects, remediated critical third-party library risks, and proactively addressed production incidents using AWS CloudWatch.
I work across Java, Spring Boot, REST APIs, Kafka, PostgreSQL, Oracle, Azure, AWS, Docker, Kubernetes, and automated testing. I bring a strong grounding in data structures, distributed systems, fault tolerance, and low-latency event-driven design.
