Senior Java Developer at Capital One who cut REST API latency by 30% through query design and caching.

United States

Message

At Capital One, I engineered Java and Spring Boot microservices for financial transaction processing and optimized REST APIs, reducing latency by 30% through query design and caching.

I also deployed cloud-native applications on AWS and implemented CI/CD pipelines with Jenkins and Git. I designed unit and integration tests with JUnit and Mockito and refactored legacy modules to improve maintainability.

Earlier, I developed enterprise applications and serverless components at Appian Corporation, and built distributed systems for credit risk analytics at Capital One. My experience also includes Java backend work at Lockheed Martin and Fannie Mae.
