React/Vue E-Commerce Site with admin

The goal is to launch a responsive e-commerce website that sells physical products and is coded entirely in either React.js or Vue.js—whichever framework you feel most comfortable maintaining long-term.

Core functionality I must have:
• Shopping cart with real-time updates
• Secure payment gateway integration
• User registration, login and profile management
• Product pages that support customer reviews

A lightweight admin area for managing inventory, orders and review moderation should be included so I can handle day-to-day store operations without touching code. Clean component structure, clear folder naming and well-commented code are important to me because I plan to keep extending the site after launch.

Please factor in mobile-first design, SEO-friendly routing and basic performance optimisation (lazy loading, code-splitting, etc.). At hand-off I’ll need the complete source, a short README explaining environment setup, and deployment guidance to a standard cloud host or VPS.
