Worked on the TheFocusTech/DomainQA repository to enhance quality assurance for critical user flows, focusing on the account deletion process without two-factor authentication. Addressed a gap in test coverage by restoring and maintaining the TC_02_04 test, ensuring this essential scenario is exercised end-to-end in the automated test suite. Utilized JavaScript for test automation and applied disciplined version control practices, including clear commit documentation and traceable changes. The work stabilized the account deletion path in continuous integration, enabling faster feedback cycles and reducing regression risk for production releases. Emphasized thorough testing and quality assurance to improve overall product reliability.
