Worked on the LimeSurvey/LimeSurvey repository to maintain stability in survey prefix handling logic, focusing on backend development using PHP. Addressed a regression by reverting changes to the private updateOtherSettings method in GeneralSettings, which impacted the codes for questions, subquestions, and answers. The approach involved a careful sequence of two coordinated commits: first reverting an attempted fix, then reverting that revert to restore the established behavior. This process preserved data integrity and ensured consistent prefix alignment across surveys. Demonstrated strong change-control practices with Git, emphasizing code review and targeted regression verification to maintain reliable survey settings logic throughout the project.
