Hasan worked on the SallaApp/theme-raed repository, focusing on improving the display of digital items on order and thank you pages. He implemented a UI cleanup that removed redundant elements such as 'files' and 'codes' for digital products, consolidating the display logic to streamline how attachments are presented. Using CSS, HTML, and Twig, Hasan aligned the frontend with updates to the digital items backend endpoint, ensuring data consistency and reducing code duplication. This refactoring centralized rendering paths, making future enhancements more efficient and maintainable. The work enhanced the user experience during checkout and clarified post-purchase digital item information.
