MLM Code With E-Commerce Module

I need a complete, production-ready MLM source code that puts user registration and management at the centre. The build must already handle user profiles, referral tracking, and strong authentication with security best practices baked in.

On top of the MLM core, an integrated e-commerce layer is required. The module should allow me to create product listings organised by category, let customers add items to a shopping cart, pass smoothly through checkout, and finalise orders through a working payment gateway connection.

Deliverables
• Full, well-structured source code
• Database schema and seed data
• Clear installation & configuration guide
• Brief walkthrough (video or document) showing user registration flow, referral capture, product purchase, and commission reflection

Any clean, maintainable tech stack is acceptable as long as the code is documented and can be extended later.
