Build Versatile Online Store

I’m preparing to launch a new store that will sell both physical items that ship worldwide and digital downloads delivered instantly. I need an experienced eCommerce developer to plan and build the entire storefront, recommend the best platform (Shopify, WooCommerce, Magento or another you trust), and make sure it’s production-ready the day we switch it on.

Core features required
• Product reviews visible on every item page
• Secure user account creation and management
• Seamless payment-gateway integration for cards and PayPal at minimum

What I expect at hand-off is a responsive, fully tested store with clear documentation so I can upload products, set prices, and process orders without extra help. Show me two or three live stores you’ve built, note which platform you’d choose for this project and why, and outline your estimated timeline from kickoff to launch.
