RedSea is a custom headless store we built with Shopify Plus, Contentful, and Next.js. Designed to serve both English and Arabic audiences, it is a multi-lang store with AR integration, RTL interfaces powerful search, omnichannel support, ‘Store Availability’ lookup, product bundles, and native cross-selling and upselling. We migrated the backend from Magento 2.3 Enterprise Cloud to Shopify Plus.
