At IQVIA, I test an enterprise Hospital Information System across clinical, administrative, and financial workflows. I validate web application workflows through functional, regression, system integration, and end-to-end testing.
For the HIS, I verify API responses and JSON/XML payloads with Postman and check application data using multi-table SQL joins. I’m also building a Java Selenium WebDriver/TestNG automation framework using the Page Object Model.
At Cognizant Technology Solutions, I tested applications in banking, telecom, retail, and travel. I reduced post-release defects by 15% through root cause analysis, and supported API testing for a Tier-1 US Aviation client using Kong API Gateway and Postman.
