Shopify Architecture & Customization - Optimized storefronts on Shopify, enforcing a modern, sophisticated aesthetic across digital assets. - Programmed custom solutions using Shopify Liquid code to eliminate theme anomalies and errors. - Integrated platform data architectures with Google Merchant Center to maximize visibility. 3.
