I have extensive experience with various test automation frameworks such as Selenium, Cucumber, and TestNG. I have also worked with tools like Jenkins for continuous integration and JIRA for issue tracking. My experience includes setting up and maintaining these frameworks, writing and maintaining automated test scripts, and integrating them into the CI/CD pipeline.

In a fast-paced environment, I prioritize tasks based on risk assessment and business impact. I collaborate closely with stakeholders to understand the critical features and ensure they are thoroughly tested. I also use agile methodologies to break down tasks into manageable chunks and adapt to changing requirements quickly.

To ensure the quality of automated tests, I follow a rigorous process of code review, continuous integration, and regular regression testing. I also emphasize writing clear, maintainable, and reusable test scripts. Additionally, I conduct periodic reviews of the test coverage to identify gaps and improve the overall test suite.

When a critical bug is found post-release, my first step is to assess the impact and prioritize a fix. I then work closely with the development team to resolve the issue as quickly as possible. Simultaneously, I ensure that the root cause is thoroughly investigated and that preventive measures are put in place to avoid similar issues in the future.

I have significant experience in cross-browser and cross-platform testing. I have used tools like BrowserStack and Sauce Labs to ensure compatibility across different browsers and operating systems. My approach includes creating comprehensive test matrices, automating cross-browser tests, and conducting manual testing where necessary to cover all critical scenarios.
