I detect and prevent payment fraud across international operations using OSINT, SQL, and transaction monitoring.

At Get Atende, a Getnet affiliate, I detect and prevent fraud across international operations in Argentina and Mexico. I investigate customer profiles with OSINT and identify suspicious behavior across e-commerce, payment links, and physical POS transactions.

I use decision trees, dashboards, SQL queries, Salesforce, Kibana, Databricks, ACI PRM, and Lynx Fraud to guide investigations and decisions. I also open and support investigations and tickets while providing guidance to the international L2 team.

My financial-services background includes executive support, dispute management, collections, financial case analysis, and accounting reconciliation. I communicate in native Portuguese, fluent English, and intermediate Spanish.
