What I'm looking for

I’m looking for a team where I can own end-to-end microservices and UI, use Java/Spring and AWS, optimize performance and cloud costs, and collaborate to ship reliably with clear impact metrics.

I’m a Full-Stack Engineer with 6 years of end-to-end experience building and owning scalable applications. I focus on measurable outcomes—improving engagement, reducing processing time, and delivering reliable platforms in production.

At Blue Yonder, I developed Java/Spring Boot microservices for rewards processing and integrated Kafka for real-time events, driving a 20% engagement boost. I also built React interfaces (TypeScript) for user loyalty dashboards and led AWS cost optimization by 30% through EC2 auto-scaling and DynamoDB migration (vs. RDS).

Previously at CVS, USA, I delivered enterprise-grade Spring Boot REST services and workflow capabilities using Java 17 virtual threads for concurrent permission validation—accelerating delivery by 60%. I designed AWS infrastructure (EC2, S3, RDS, ELB, Auto Scaling, CloudWatch) and CI/CD pipelines in Jenkins with Docker & Kubernetes, while optimizing databases across Oracle SQL and MongoDB.
