React-Blockchain Ecommerce Build

I am launching a new ecommerce site and want the entire stack built with React on the frontend and Node.js on the backend. The project must be production-ready, scalable, and, most importantly, include a fully functional payment gateway integration so customers can check out smoothly and securely.

Here’s the flow I have in mind:

• React powers a fast, responsive storefront that lists products, handles the cart, and guides users through checkout.
• Node.js (with Express or a comparable framework) delivers the API, manages business logic, and connects to a SQL or NoSQL database for product, order, and user data.
• The payment gateway (Stripe, PayPal, or another modern provider—open to your recommendation) is set up in both sandbox and live modes, with webhook handling for real-time order confirmation.

Deliverables
1. Clean, well-documented code in a public Git repository.
2. Secure payment workflow tested end-to-end.
3. Basic admin panel or route to view orders and update inventory.
4. Deployment instructions (Docker, Render, AWS, or similar) so I can spin up the app with minimal effort.

Acceptance Criteria
• A test transaction in sandbox mode completes without errors.
• Orders appear in the database with correct status updates from payment webhooks.
• The React UI loads in under three seconds on a typical 4G connection.

If you have prior experience connecting React/Node builds to modern payment gateways and can move quickly, I’d love to see your approach and timeline.
