Lead Java Engineer at WITHmyDOC who built healthcare microservices that cut API response times by 40%.

At WITHmyDOC, I architected and implemented cloud-native Java and Spring Boot microservices for healthcare applications, improving scalability and reducing API response times by 40%. I also optimized Azure Cosmos DB schemas and ingestion patterns, lowering monthly cloud costs by 30%.

I built secure backend services and REST APIs integrating mobile applications, Garmin and Fitbit services, and Bluetooth medical-device telemetry. I also worked on Kubernetes deployments, Jenkins CI/CD pipelines, Kafka messaging, and Keycloak IAM.

At DTCC, I designed and developed enterprise Java applications for financial-services operations. I re-engineered a critical batch-processing system, reducing its execution time from approximately nine hours to nine minutes, and supported the IBM WebSphere migration. I'm currently providing software architecture and technical consulting while continuing hands-on Java development.
