Java Full Stack Developer at Citi building secure banking microservices and reducing transaction latency by 25%.

United States

Message

At Citi, I develop Spring Boot microservices and REST APIs for banking transaction workflows. I strengthened authorization with Spring Security, JWT, and RBAC, reducing security-related defects by 15%.

I also tuned SQL queries and Hibernate mappings across PostgreSQL and Oracle, reducing average transaction latency by 25%. I build Angular components integrated with backend APIs and write unit tests as part of Agile/Scrum work.

Previously, at Elevance Health, I developed healthcare services and secure API integrations, and worked on Kafka and JMS workflows and AWS deployments. On my Microservice Project, I built an e-commerce platform with Spring Boot services, React, Kafka, and Redux.
