Senior🎓
Top SchoolGreg Roll is a Senior Technical Product Manager with 20+ years building resilient payments and revenue systems that quietly handle high-volume, mission-critical transactions. He has architected multi-PSP infrastructures, processor integrations (Trustly, Paysafe, Braintree, PayPal/ Venmo, Klarna, Interac), and KYC/AML and fraud workflows that supported launches across 20+ U.S. regions and multi-million-dollar daily volumes. At PENN he drove payment strategy for a North American sportsbook/casino launch, built card-processing redundancy that ensured failover reliability, and delivered $10.5M in cloud and observability cost savings. Greg blends deep technical roots (former senior developer) with product leadership to improve SDLC, documentation, and agile practices so teams ship reliably. He’s especially interested in applying AI to boost authorization rates, identity intelligence, and compliance automation rather than just cutting costs. Based in Calgary, he connects pragmatic engineering with risk-aware product strategy to keep fintech services working under pressure.
