At Fiserv on the Omnipay Platform, I support certification testing, production releases, and end-to-end regression for merchant acquiring and dispute modules. I validate Visa and Mastercard mandates, PCI DSS requirements, ISO8583 messaging, REST/JSON integrations, and backend payment workflows.
I've also delivered QA work at Cognizant for Fiserv Omnipay, Sallie Mae Bank, and Fiserv Output Solutions. I use SQL, Python, GitHub Copilot, and Agile practices to investigate defects, build QA productivity tools, improve regression coverage, and mentor junior QA analysts.
