Custom E-Commerce Platform Development -- 2

I’m building a modern, end-to-end e-commerce ecosystem that covers web, Android, and iOS. The stack is already defined—React.js and React Native on the front, Node.js with Express.js in the middle, and MongoDB underneath—so you’ll be working in familiar, JavaScript-centric territory. REST-style APIs will connect the layers, and everything must be responsive, secure, and ready for real-world traffic on day one.

Core business goal
The platform will serve as my primary online store. From first click to final payment, shoppers need a seamless journey that also feeds clean data to an admin dashboard for analytics and automation.

Essential storefront features
• Product catalog with powerful search
• Shopping cart and checkout flow that plugs into at least one mainstream payment gateway
• User reviews and ratings visible on each product page

Authentication requirements
• Traditional email + password
• One-tap social logins
• Optional two-factor authentication for higher-risk actions

Beyond the basics
An admin panel should let me manage inventory, promotions, users, and content. I also need hooks for third-party APIs—shipping, marketing, CRM, and an AI module for personalised recommendations and business-rule automation. Every endpoint must follow best-practice security and be documented for future integrations.

When you respond
Show me two or three live projects from your portfolio that prove mastery of React/React Native, Node/Express, and MongoDB at scale. Outline a high-level timeline with key milestones, and include a single, all-in project price (broken down by phase if you like).
