React E-Commerce Single-Page Application Build -- 2

I’m building a single-page e-commerce platform from the ground up and need an experienced React developer who can take full ownership of the front-end. The core stack is React 17+ with modern JavaScript (ES6+); you’ll architect reusable components, wire up state management, and ensure the customer journey stays lightning-fast and glitch-free.

Key requirements
• Secure user authentication—social logins and email/password flows, protected routes, token refresh, etc.
• Real-time updates for inventory, cart totals, and order status via WebSockets or a comparable solution.
• Fully responsive design that feels native on desktop, tablet, and mobile, meeting current accessibility guidelines.

You’ll collaborate with our back-end lead over GitHub, document components with Storybook (or a tool you prefer), and cover critical logic with unit tests. I’m looking for clean, readable code, performance-minded decisions, and clear communication on progress.

Deliverables will be:
1. A production-ready SPA in React with routing, state management, and theming in place.
2. Complete auth flow integrated with our API.
3. Real-time data layer showing live stock and order updates.
4. Responsive UI that passes Lighthouse mobile performance ≥90.
5. Setup instructions and hand-off documentation.

If you thrive on crafting polished UIs and solving real-time challenges, let’s talk and get this store live.
