Dynamic professional skilled in chargeback dispute resolution and fraud detection.
What I'm looking for
I am a dynamic and proactive professional with a Bachelor's degree in Tourism, specializing in social dimensions. My experience spans chargeback dispute resolution, fraud detection, and transaction risk analysis, where I have successfully leveraged data insights to enhance risk mitigation and ensure regulatory compliance. I take pride in my strong track record of increasing chargeback win rates, demonstrating my commitment to excellence in customer service.
In my role as an Independent Consultant - Chargeback Operations Analyst, I analyzed account behavior from a fraud and ID theft perspective, utilizing platforms such as Shopify and Accertify. I effectively increased the operations win rate from 28% to 60% by providing compelling evidence in disputes. My previous experience at Teleperformance as a Chargeback and Dispute Analyst allowed me to hone my skills in reviewing and processing fraud cases, ensuring compliance with financial regulations, and maintaining detailed records of dispute cases.
