What I'm looking for

I’m looking to drive fraud prevention and dispute resolution with strong regulatory compliance—using MIS reporting, dashboards, and data analysis to reduce financial exposure, improve TAT, and build reliable chargeback workflows.

I’m a Senior Fraud Operations professional focused on dispute resolution, chargeback lifecycle management, and fraud prevention. I’ve processed Mastercard chargebacks and managed Visa disputes using defined reason-code frameworks, while maintaining accuracy and TAT compliance and proactively flagging compliance risks.

At Wells Fargo and HCL Technologies, I built MIS reporting and operational dashboards to help leadership make faster decisions, and I improved workflows through cross-functional collaboration. I also contributed to fraud prevention process improvement, supporting a reported 15% reduction in resolution time, and authored a 30-page Visa reason code reference guide.
