At Global Payments, I own end-to-end QA strategy for a complex credit and debit payment host, validating authorizations and completions for Visa, Mastercard, and Amex. I deliver bi-annual card-brand compliance certifications before production deployments and use FIS/Clear 2 Pay, Rally, Oracle SQL, and UNIX logs to produce audit-ready test evidence.
Previously at Excentus, I validated loyalty marketing software across client environments, built production-like POS and fuel-pump test labs, and trained seven QA analysts. I've worked across functional, regression, integration, smoke, API, UAT, and end-to-end testing in Agile Scrum teams.
