AI-Ready Multi-Tenant E-commerce

I need a full-stack solution that lets me spin up and manage multiple independent online shops from one codebase. Each tenant should get its own storefront, products, and checkout flow while I control everything from a single super-admin portal.

The must-haves are:
• An AI layer that serves real-time personalised recommendations on every storefront.
• Core e-commerce flow with a reliable shopping cart and visible customer reviews.
• Responsive front ends for Web, native iOS, and native Android so shoppers enjoy the same experience on any device.

I’m open to the tech stack you prefer—Laravel, Django, Node, Flutter, React Native, or something comparable—as long as it scales cleanly, supports future plugin modules, and keeps page loads fast.

Please outline how you’ll:
1. Design the multi-tenant architecture (database isolation, theme overrides, tenant-level analytics).
2. Train or integrate the recommendation engine.
3. Deliver Web, iOS, and Android builds from a single codebase or coordinated repositories.
4. Hand over documentation and a test plan so I can validate every feature before launch.

If you already have a boilerplate or SaaS skeleton that fits, say so; it could shorten delivery time.
