Message

At Remitly, I manage end-to-end chargeback disputes through payment and bank portals. Across 964 cases, I achieved a 56.33% win rate and recovered $209,778.12.

I was a key contributor to the 2025 Dispute Reference Document deployment, optimizing rebuttal evidence packages against Visa and Mastercard standards. I also coordinated urgent fund recalls with financial institutions and investigated fraud indicators including account takeover and financial elder abuse.

Previously, I applied enhanced due diligence to high-risk profiles at Remitly and reviewed banking disputes at Foundever / Sitel. My work has included identifying fraud patterns, validating customer documentation, and resolving cases in line with compliance requirements.
