Evailson Barbosa enhanced product attribute handling in the deco-cx/apps repository by introducing type and id fields to the additionalProperty structure, enabling richer and more descriptive product data. He updated the GraphQL schema to support this expanded attribute model and implemented corresponding data transformation logic using TypeScript. This work focused on improving the expressiveness and downstream usability of product attributes, ensuring that the new data shape was consistently represented across the application. While no major bugs were addressed during this period, Evailson’s efforts centered on data-model enrichment and aligning backend and frontend systems through careful schema and transformation updates.
