E-Commerce Website & App Build

I want to launch an online store that works seamlessly on web browsers and as a dedicated mobile app. The core catalogue will start with home-goods products, so clean category navigation and intuitive product filters are vital. I also need a secure shopping-cart flow that supports multiple items, calculates totals in real time, and connects smoothly to standard payment gateways.

The website and the mobile app should share a single back-end so inventory, orders and customer data stay perfectly in sync. A modern, responsive front-end is important—think fast loading times, clear imagery, and a checkout that needs as few taps or clicks as possible. If you have a preferred framework or e-commerce engine (Shopify, WooCommerce, Magento, Laravel, React Native, Flutter, etc.), let me know; I’m open to whichever stack delivers stability and an easy-to-manage admin area.

Deliverables:
• Fully functional website storefront with product filters and shopping cart
• Companion iOS and Android apps tied to the same database
• Admin dashboard for adding products, photos, prices and promo codes
• Payment gateway integration and order confirmation emails
• Basic hand-over documentation plus a quick walkthrough session

Please include examples of previous multi-platform shops you’ve built and tell me how quickly you can have a first version ready for testing.
