About

I've led enterprise platform modernization for Pine Labs, Autodata, Deutsche Bank, Frys.com, LendingPoint, and healthcare clients, building scalable microservices, secure APIs, and high-availability cloud deployments. Most recently, I architected Pine Labs' centralized billing platform for pricing, invoicing, receivables, statutory integration, and enterprise payment workflows. Across 17+ years, I've modernized monoliths into microservices, delivered HL7 FHIR R4 healthcare integrations, optimized search platforms, and established architecture governance, code review standards, and CI/CD practices. I work hands-on with Java, Spring Boot, AWS, Kubernetes, and DevOps automation while leading Agile delivery for global clients.
