Worked on backend refactor stabilization for the mindlogger-backend-refactor repository, focusing on resolving a critical bug in applet duplication. Addressed an issue where the auto_assign property was not preserved for activities and activity flows during duplication, thereby improving data integrity and reducing the risk of incorrect assignment behavior. Utilized Python for backend development, implementing targeted test adjustments to account for daylight savings timezone offsets and ensure robust duplication logic. All changes were validated and documented with traceable commits, supporting ongoing refactor efforts. The work demonstrated attention to detail in backend workflows and contributed to the reliability of applet management processes.
