Operations and Risk Management professional at Citicorp improving fraud resolution and transaction reconciliation.

India
Message

At Citicorp Services Pvt. Ltd., I review operational performance, identify process gaps, and support data-driven decisions with reporting and analytical insights. I also perform risk assessments for sensitive financial operations, with attention to internal controls and customer protection standards.

Previously, as an Operations Supervisor Analyst at Citicorp Services Pvt. Ltd., I investigated credit card fraud cases using Pega, AIP, IBS AWS, and Workdesk. I prepared fraud analysis reports and reconciled approved and declined transactions; a transaction reconciliation enhancement reduced unresolved operational cases by 20% month-over-month.

At Barclays Global Services Pvt. Ltd., I managed payment settlement reconciliation and supported AML/KYC reviews. I also audited and remediated 5,000+ KYC/AML files as part of a documentation quality initiative.

At Fiserv India Pvt. Ltd., I led a 12-member card operations team serving 150+ U.S. banking clients and improved SLA adherence above 95%. Earlier at Wipro Ltd., I handled chargebacks and disputes for Capital One credit card services and conducted transaction risk reviews and fraud investigations.
