During a two-month period, amxmodx.unloco@gmail.com enhanced PrestaShop’s cart and upgrade workflows by developing modular, hook-driven features and addressing targeted bugs. In PrestaShop/PrestaShop, they refactored the cart duplication process using PHP and object-oriented programming, introducing hooks that enable extensibility and ensure accurate session handling during checkout. They also resolved a product image display issue by improving SQL-based matching logic for customized orders. In PrestaShop/autoupgrade, they implemented a new SQL-driven post-duplication hook to automate upgrade tasks and reduce manual intervention. Their work demonstrated depth in backend development and database management, resulting in more reliable and extensible e-commerce operations.
