At Wirecard, I managed fraud prevention operations for more than 200 merchants across diverse eCommerce sectors, from travel to digital goods. Rising online fraud created pressure to protect revenue streams without disrupting customer experience, and my role was to design scalable mitigation strategies, strengthen compliance, and foster cross-team coordination.

I developed fraud rule sets using tools such as Ethoca, Fraugster, and ThreatMetrix, trained merchant support and compliance teams, and consulted directly with clients to refine their fraud strategies. I also ensured adherence to PCI standards and regulatory requirements, embedding compliance into everyday operations.

These efforts reduced fraud losses and chargebacks, standardized playbooks that improved response times, and reinforced trust across sales, risk, and technology teams. The frameworks I helped design scaled with Wirecard’s growing merchant base and positioned the company as a reliable partner in risk management.

This project taught me the importance of staying calm under pressure and bridging business, compliance, and technical needs. More than just reducing fraud, the work demonstrated how proactive risk management safeguards trust and creates the foundation for sustainable growth.
