At USBank, I develop and maintain Hogan CIS, DDA, and TDA modules for core banking applications. I implemented KYC tokenization logic in Hogan and enhanced batch processing for account conversions, balance updates, and statement generation.

Previously, I developed mainframe applications for insurance, banking, and retail at MetLife, PNC Bank, Cognizant Technologies, Wipro Ltd., and Axis Studio. My work has included claims and loan processing, CICS transactions, and integrations with external systems using COBOL, JCL, DB2, and related mainframe technologies.
