We executed an end-to-end eCommerce UI/UX redesign focused on driving engagement and conversions. The build followed a mobile-first development approach using React and Tailwind CSS, ensuring smooth functionality across devices. A smart search system with predictive filters was introduced to enhance product discovery. We also enabled live stock synchronization and integrated a click-and-collect module to improve the purchase journey. The backend was connected with ERP and fulfillment APIs for seamless operations, while the Shopify Plus-powered one-click checkout simplified the final step for users. Finally, we ensured speed optimisation and thorough QA testing to deliver a fast, stable, and conversion-ready platform.
