Risk and Fraud Analyst at Libertex Group investigating suspicious activity and transaction-monitoring alerts.

Colombia

Message

At Libertex Group, I investigated suspicious account activity, transaction-monitoring alerts, and potential financial crime across LATAM, Europe, and Central Asia. I identified fraud patterns and managed investigations through risk-based account decisions.

At CSG Forte, I assessed merchant applications for payment processing and acquiring services. I identified a suspected business impersonation application, verified the activity with the legitimate business owner, and escalated the findings.

At Keep, I conducted business onboarding reviews and made approval or rejection decisions for Canadian businesses, sole proprietorships, and merchants. I also completed periodic customer risk reviews and adapted internal SOPs to reflect policy changes.

At One Link/Webhelp, I investigated fraud claims and payment disputes, reviewing customer evidence alongside account information and transaction records. My work has included AML/KYC compliance, suspicious activity narratives, and blockchain fundamentals.
