Worked on the magento/magento2-page-builder repository to enhance the reliability and efficiency of automated test suites for video background validation. Focused on stabilizing MFTF tests by increasing wait times for video visibility and later optimizing action groups to remove unnecessary waits, ensuring tests only proceed when video backgrounds are visible. This approach reduced test flakiness and accelerated feedback cycles, supporting safer and faster releases. Utilized XML and the MFTF framework to implement these improvements, demonstrating skills in test automation and reliability-focused testing. The work resulted in a more deterministic and efficient CI process for front-end video background scenarios in Magento.
