I've built full-stack applications at Zensar, LanceSoft, CData, and Capgemini using Java, Spring Boot, Angular, React, and distributed systems. At Zensar, I'm leading a WildFly-to-Spring Boot microservices migration that improved application performance by 30% while reducing maintenance costs.

I've delivered REST and GraphQL APIs, Kafka event streaming, CI/CD pipelines, automated testing, and cloud deployments on AWS and GCP. I also mentor junior engineers, resolve production incidents, and built systems that improved operational efficiency, data quality, and user engagement.
