At Diusframi, I analyze and validate fraud alerts and chargebacks under Visa and Mastercard rules. I also coordinate merchant evidence and follow disputes through resolution within legal deadlines and SLAs.
At Klap S.A., I managed fraud, merchant risk, and AML/CTF controls, reducing losses by 100% compared with the previous period. I optimized Monitor Plus rules, reducing false positives by 80%, and analyzed transaction data to identify anomalies and track fraud KPIs.
At Transbank S.A., I designed and implemented risk alerts that increased fraud detection by 120% and suspicious transaction reports by 100%. I also contributed to implementing IBM i2, moving from manual analysis to visual network analysis to identify connections between merchants.
