For Arcshop, an online retailer specializing in a wide range of bathroom and home furnishings, my involvement went beyond standard Shopify theme design, to implement extensive, advanced customizations, including the development of a real-time delivery time calculator for end-users and bespoke modules for managing related products. A significant focus was also placed on a comprehensive UI/UX optimization of the product page and substantial enhancements for Page Speed Insights parameters, ensuring an exceptionally performant and intuitive e-commerce experience.
