My work has directly contributed to: • Millions in annual fraud loss prevention • €1M+ in scam losses averted in one year at AIB • ATO resolution time reduced by 80%+ at Square • And a first-of-its-kind monitoring system for high-risk & velocity new merchants at Squarespace. I specialize in: Fraud & Credit Risk Analysis Trust & Safety Escalation Processes ATO Policy Design Risk Ops Optimization Cross-functional Alignment between Risk, Product & CS I thrive in fast-paced, high-accountability environments where attention to detail, calm under pressure, and strategic foresight are non-negotiable. I’m also passionate about training, building trust across teams, and leaving every system I touch better than I found it. Open to connecting with global teams solving complex fraud, compliance, or trust challenges — especially those who value autonomy, innovation, and strong risk culture. Let’s connect.
