Fraud, Servicing, Collections, Chargebacks expert

Consultant – Chargebacks, Fraud, Customer Service, Collections I have multiple areas of expertise. Over the last 7 years I have developed operational expertise in chargeback, payments, and fraud processes that include Stripe and Radar, Kount, Shopify, PayPal, and Klarna. If you have fraud exposure and need help in shoring up your controls as well as chargeback responses, I am your guy. I further have led call centers remotely, including Relevant Ads, Merani Law LLC,, as well as on-site centers for Toyota Financial Services and Capital One. Systems I have utilized include Salesforce, Zendesk, Zoho, Shopify, and others. I have provided call center and campaign management for multiple organizations. This has involved call routing IVR, skilling, call center and collections metrics and reporting. I further have gotten in the weeds taking calls, including escalations, and coached agents on NPS satisfiers and professional call handling. I am certified in Claude and Gemini AI, and utilize it daily for tasks and coding. Ask me about how I can automate your processes and increase efficiency while also applying my extensive operational knowledge.
