Design, develop, maintain, and execute automated tests for web applications, mobile applications, APIs, and backend services.
Build and enhance scalable, maintainable automation frameworks using tools such as Playwright, Selenium, Appium, or equivalent technologies.
Analyze functional requirements, user stories, and technical specifications to develop comprehensive test strategies and test cases.
Apply risk-based testing techniques to identify critical business scenarios, boundary conditions, and potential defects.
Leverage AI-powered tools to generate, refine, and optimize test cases, test data, and automation scripts.
Design automated tests covering functional, integration, regression, and end-to-end testing.
Integrate automated tests into CI/CD pipelines to provide continuous quality feedback.
