Oliver Menal worked on the KYH-Net23/Rika repository, focusing on front end development to enhance ecommerce user experience and streamline returns processing. Using React, JavaScript, and JSX, he revamped the product details page with a new UI, color palette selection, wishlist and add-to-cart actions, and admin edit controls, while also cleaning up redundant options. He introduced a dedicated returns route and a ReturnFromPayment component featuring a loading state and clearer email confirmation messaging. His incremental, feature-branch workflow enabled efficient QA and deployment, reducing user friction on product pages and simplifying post-purchase processes, though the work was limited in scope and duration.
