Project description. I built and delivered a full multi-category eCommerce marketplace for a real client from scratch using modern full-stack development. The platform includes categories like toys & games, sports & outdoor, school & office supplies, beauty & personal care, and pet supplies. It features product sections (popular, latest, best selling, deals), shopping cart, checkout system, newsletter, contact/support system, and fully responsive design. Built with MERN stack (React.js, JSX, Tailwind CSS, Node.js, Express.js, MongoDB). The website is SEO friendly, fast, and production ready.
