I’m ready to give my existing e-commerce site a fresh start in React.js. The core objective is simple: keep selling seamlessly while switching to a modern, component-based front end. Must-haves • Build the entire storefront in React.js from my current design and content. • Implement a secure, production-ready payment gateway integration. I’m open to PayPal, Stripe, Square, or your recommended option—help me choose the best fit and handle the full setup (API keys, test mode, live mode). Nice-to-haves If you can also streamline the product catalog or shopping cart while you’re in the codebase, let’s discuss; my priority is still the payment flow. Deliverable A GitHub repo (or similar) with clean, documented React code, a working payment gateway in both sandbox and live environments, and instructions for deployment so I can push it straight to my hosting. I’ll provide current site access and any design assets you need. Looking forward to seeing how you can modernize the stack and get transactions running smoothly.
