React Next.js E-commerce Site

I’m ready to launch a modern, fully responsive e-commerce website built with React and Next.js. The store will feature a clean product catalogue, add-to-cart flow, and a fast, SEO-friendly storefront powered by Next.js routing and server-side rendering. Key requirements • Payment processing through PayPal from checkout to order confirmation. • Secure customer accounts so shoppers can register, log in, view order history, and manage personal details. • Adaptable UI that looks and performs flawlessly on mobile, tablet, and desktop screens. • Codebase organised with reusable React components, clear state management, and TypeScript preferred for type safety. • Admin-ready product and order structures (dummy data or simple dashboard is fine for now; I’ll expand later). Deliverables 1. Source code in a Git repo with concise setup instructions. 2. Deployed demo (Vercel or similar) to verify responsiveness, PayPal flow, and account creation. 3. Brief hand-off document covering environment variables, PayPal sandbox/live switch, and next steps for scaling. Acceptance criteria – PayPal test transaction completes without errors. – New users can register, receive a confirmation email, and log back in. – Core pages (home, collections, product detail, cart, checkout, account) score 90+ on Lighthouse mobile performance. If you have experience combining React, Next.js, and e-commerce best practices, let’s make this store launch-ready.
