Worked on stabilizing the test suite for the mozilla/gecko-dev repository by addressing persistent flakiness in Linux BiDi screen orientation WebDriver tests. Applied a targeted patch using Python to disable four unreliable tests, reducing continuous integration noise and improving the reliability of sheriff feedback loops. Focused on debugging and test automation, the approach minimized risk by avoiding broader changes to the test suite while a long-term solution is developed. Demonstrated familiarity with Linux CI environments, WebDriver infrastructure, and BiDi emulation challenges, collaborating across repositories to triage and mitigate flaky test failures and maintain a stable development workflow for contributors.
