I need a complete e-commerce website built with the MERN stack—MongoDB, Express, React, and Node.js—from the ground up. The project covers both front-end and back-end work, leading all the way to a production-ready deployment. Core features must include: • Product search and filter that remains fast at scale • Customer reviews and ratings tied to individual product pages • Secure payment gateway integration (Stripe, PayPal, or another reliable option) • Proper responsiveness so the site looks and functions flawlessly on mobile, tablet, and desktop Clean, modular code, well-structured APIs, and thoughtful database design are essential. Please pay attention to best practices for security, accessibility, and SEO fundamentals. In your proposal highlight the experience that makes you confident you can deliver a smooth, high-performance MERN solution—especially prior work on e-commerce or similarly complex apps. A concise overview of your relevant projects and the specific challenges you solved is exactly what I’m after. I’ll handle product data and copy once the framework is in place; you’ll provide the full source code, installation notes, and a short hand-off session to walk me through deployment.
