Worked on the PrestaShop/PrestaShop repository to enhance the module system’s extensibility and upgrade reliability through targeted back-end development. Built and integrated new lifecycle hooks in PHP, enabling event-driven custom logic during module enable, disable, and upgrade actions. Improved the sequencing of upgrade hooks to ensure they execute only after the database version is updated, reducing upgrade risks and supporting more predictable module behavior. Added a pre-update configuration hook to allow validation or custom processing before configuration changes. These features collectively empower merchants and developers to better govern configuration updates and extend module functionality using robust backend and module development practices.
