React.js Ecommerce Platform Build

I need an experienced React.js developer to turn my e-commerce concept into a fast, reliable web application. All UI mock-ups and backend APIs are ready; your role is to create the customer-facing interface—from product catalogue and item details to cart and checkout—using modern React (hooks, functional components, ES6+).

Clean architecture, reusable components, and mobile-first responsiveness are must-haves. Please optimise load times with techniques such as code-splitting and lazy loading, and keep accessibility top of mind while you style the app (Tailwind, Material UI or similar).

Deliverables
• Complete React.js codebase hosted in a Git repo
• README with local setup, build, and deployment steps
• Short demo or screen-cast confirming all core flows work (browse, add to cart, checkout)

If you love crafting polished e-commerce experiences and can keep communication clear and timely, I’m excited to see how you’d approach this build.
