Developed a CQRS-based module installation and upload workflow for the PrestaShop/PrestaShop repository, focusing on backend development and module lifecycle improvements. The work introduced new command handlers, command classes, interfaces, and exceptions in PHP, establishing a decoupled architecture that enhances scalability and traceability. By updating the module manager to support uploads and enabling remote zip source handling for application/octet-stream content types, the solution allows for binary module transfers and broader integration. This foundation supports improved auditability, rollback capabilities, and parallelizable operations, reducing deployment risks and future-proofing module management within the PrestaShop ecosystem through robust backend and CQRS practices.
