• Run tests through Azure DevOps Pipelines and actively contribute to enhancements in CI/CD processes.

• Verify idempotency and retry logic in essential operations.

• Employ robust selectors (data-testid, accessibility locators) in E2E testing scenarios.

• Execute tests in local Linux/CLI environments.

• Suggest enhancements to test coverage, automation, and QA processes rather than merely executing tests.
