Message

At JPMorgan Chase, I own full-stack feature design and delivery using Java, Spring Boot, React, and AWS. I design and deliver microservices and REST APIs for enterprise workflows and integrations.

I lead development activities for a 3–4 engineer team, supporting sprint planning, task breakdown, code reviews, and release readiness. I also mentor engineers and help standardize squad practices.

My work includes AWS Lambda functions and Amazon EventBridge integrations, as well as Kafka-based services and downstream integrations. I’ve also driven CI/CD improvements, test strategy, and engineering quality through reviews and automation.

Earlier, I delivered Java and Spring services for banking and payments clients, including Mastercard, USAA, UBS, and Standard Chartered Bank. I hold AWS Certified Cloud Practitioner and Sun Certified Java Programmer & Web Component Developer certifications.
