Managed end to end chargeback prevention and dispute resolution for high volume ecommerce merchants processing over $40M annually through Stripe and major payment gateways.

Built custom Stripe Radar rule sets and automated risk filters that significantly lowered friendly fraud and card testing attacks. Led the optimization of pre dispute data delivery systems, enabling banks to auto resolve claims before they reached the merchant dashboard. Maintained merchant dispute ratios consistently below the critical 1.5% Visa threshold across multiple high risk verticals. Trained internal teams on evidence packaging, 3D Secure strategies, and velocity rule management. Collaborated directly with payment processors and issuing banks to strengthen first-party fraud defenses. Key achievements: • Reduced average monthly chargeback volume by 58% • Eliminated over $280,000 in annual dispute related losses • Improved merchant account stability and processor approval rates • Developed scalable risk frameworks later adopted across multiple client portfolios This role strengthened my expertise in turning reactive dispute handling into proactive, bank level protection systems.
