Mahesh Nagam
@maheshnagam
I investigate financial crime, improve AML operations, and lead high-performing analyst teams.
IndiaWhat I'm looking for
I've investigated fraud and financial crime across Amazon's global marketplaces and Cognizant's AML operations, making risk-based decisions on transaction laundering, account takeover, card testing, merchant fraud, refund abuse, and cross-border payment fraud.
At Cognizant, I serve as a Subject Matter Expert and Acting Team Lead for a 50+ analyst operation. I manage queues, SLAs, escalations, quality audits, coaching, and process improvements, sustaining 98%+ SLA adherence while reducing case rework by about 30% and improving decision accuracy by about 20%.
Previously at Amazon, I reviewed and resolved 100+ fraud cases daily across NA, EU, and IN marketplaces, maintaining 96%+ case accuracy. I also authored fraud detection playbooks, collaborated with Risk, Payments, Trust & Safety, and Legal teams, and helped reduce manual review effort for low-risk segments.
I combine hands-on investigation expertise with SQL, Python, and machine-learning analysis. I built a fraud detection system using Scikit-learn, SMOTE, Random Forest, and XGBoost that achieved a 98.5% AUC-ROC.
