I build and modernize enterprise Java systems, cloud platforms, and payment microservices.

At Marsh McLennan, I develop Velocity platform modules for enterprise clients including Amazon, FedEx, and Motor Carrier, while modernizing legacy applications with Spring Boot and modern Java.

Previously at MetLife, I led the Legacy Modernization program, migrating insurance systems to Azure and reducing infrastructure costs by 70%. I also moved the stack from Java 8 to Java 21, Cordova to React Native, and ApiG to Azure API Management, accelerating release cycles by 50%.

At BlumonPay, I built Spring microservices for 8K–10K daily payment transactions and led a reconciliation service that cut Finance processing from 8–10 hours to 1–2 hours per cycle. I bring hands-on experience in production support, cloud integrations, CI/CD, databases, and full-stack delivery.
