I test enterprise payment, iGaming, and transportation platforms from UI through backend integrations.

At PaymentUS, I tested large-scale bill payment systems across migrations, scheduling, chargebacks, refunds, REST APIs, databases, payment processors, POS devices, and EMV/NFC workflows. I built and maintained automated UI suites with Java, Selenium WebDriver, TestNG, and UI Vision while managing release readiness in Jira and Xray.

Previously, I validated online gaming platforms at Stars Group and fleet-management workflows at Fleet Complete, covering desktop, mobile, web, integrations, localization, compliance, and production release sign-off. I've also developed automation frameworks and performed performance, scalability, and 500-user load testing at PTC and Sandvine.
