At Tata Consultancy Services (TCS), I perform manual and automation testing for enterprise applications, developing and maintaining 40+ test scripts with Core Java, Selenium WebDriver, and TestNG. This work cut manual regression effort by roughly 30%, and I integrated automated test execution into Jenkins pipelines for nightly regression runs.
Across Bank of Maharashtra banking modules, I test transaction and customer-management workflows and validate financial services APIs with Postman. In Ericsson's telecom work, I tested 4G/5G modules and contributed to a 20% reduction in recurring defects through defect triage and root cause analysis.
