Message

At Cognizant, I develop and maintain end-to-end UI automation with Playwright and TypeScript, covering functional and regression testing. I also create reusable automation methods for common browser interactions.

I use Claude AI and GitHub Copilot to accelerate test development, troubleshoot failures, and refactor repetitive code, then review AI-generated scripts for reliable locators, assertions, and maintainability. My work also includes REST API automation with REST Assured and Java, and Selenium WebDriver automation integrated with GitHub Actions.

In banking, I prepared test data and scenarios for deposit account opening and digital lending workflows. Earlier, I automated Salesforce service-side functionality at Tata Consultancy Services (TCS) and built Selenium-based tests for SAP warehouse management and store management applications.
