Full-Stack Ecommerce Website Build

I need a production-ready online store that sells physical products and feels as smooth on mobile as it does on desktop. Core pages—home, category, product detail, cart, and checkout—should load quickly, pass basic Core Web Vitals, and be wrapped in a modern, conversion-friendly design.

Key features I definitely want included:
• A customer Wishlist that syncs instantly across devices once a shopper is logged in.
• Real-time inventory updates pulled automatically from my suppliers’ feeds or APIs so shoppers never see an out-of-stock item.

Payments must support credit/debit cards and PayPal out of the box, with the option to add Apple Pay later. Shipping rules will be flat-rate to start, but the platform should let me bolt on real-time carrier rates when we scale.

Please build on a platform that can grow—Shopify Plus, WooCommerce with robust hosting, or a headless setup with Next.js and a commerce engine behind GraphQL are all fine with me as long as the final stack is documented. I’ll need admin access, a short hand-over video, and step-by-step instructions on how to add products, run promotions, and read basic analytics.

Before sign-off, I’ll test:
1. Wishlist persistence across logins and devices
2. Sync accuracy against a sample supplier feed (provided)
3. Successful test orders through the payment gateway

Launch target is six weeks from hire, but I’m flexible if we agree on phased milestones. If you have questions about the supplier API or need sample CSVs, let me know and I’ll send them right away.
