I need a full-featured online store built from the ground up, including both the customer-facing site and the entire backend that powers it. The storefront must look polished, load quickly on any device, and guide shoppers smoothly from product discovery through secure checkout. On the server side I expect clean, well-documented code that handles inventory, orders, payments, shipping calculations, discount logic, and basic analytics. Core functions such as user accounts, a searchable product catalog, multiple payment gateways, tax/shipping rules, and automated email notifications are non-negotiable. Features like product reviews or live-chat support would be great additions if they fit naturally into the build.

• Responsive front-end with branded UI/UX
• Fully functional admin panel (inventory, orders, customers, promos) 
• Payment and shipping integrations tested in sandbox and live modes
• Documentation covering setup, deployment, and day-to-day operations
• One brief knowledge-transfer session after launch
