At Centene Corporation, I develop COBOL applications for Medicare Advantage and Medicaid claims adjudication. I integrated mainframe processing with cloud analytics through IBM MQ, Spring Boot, AWS S3, and REST APIs, and improved DB2 performance by 30%.

At Citibank, I optimized securities settlement systems, reducing the batch window by 40% and MQ message failures by 35%. Earlier at Infosys Limited, I developed banking and insurance applications and maintained Hogan Core Banking and customer statement systems.
