Build Full-Stack E-Commerce Website | Blend of Flipkart, Shopify, Amazon & Alibaba

I am looking for an experienced full-stack developer/team to build a modern, scalable e-commerce platform entirely from scratch.
This platform should be a blend of Flipkart, Shopify, Amazon, and Alibaba — combining marketplace features, seller dashboards, customer experiences, and B2B/B2C workflows.

Important Note: We want to minimize the use of outsourced APIs, prebuilt SaaS tools, or drag-and-drop solutions. The goal is to maximize self-built features to ensure flexibility, independence, and full control of the platform.

Core Features (Phase 1 - MVP)

Multi-category product listings

Seller dashboard (add/manage products, track orders, view analytics)

Customer accounts (wishlist, cart, order history, reviews)

Cart + Checkout flow

Secure, self-built payment integration (with Razorpay/Stripe/UPI at core level, not 3rd party plugins)

Responsive design (mobile-first, Tailwind/Bootstrap preferred)

Search, sort & filtering options

Basic inventory + order management

Advanced Features (Phase 2)

Marketplace model (multi-seller, commission system like Amazon)

Custom seller storefronts (like Shopify)

Recommendation engine (basic AI/algorithmic suggestion system)

Multi-language & multi-currency support

SEO-optimized product pages

Integration with warehousing/logistics APIs (future stage, if needed)

Technology Preferences

Frontend: React.js (Vite/Tailwind) or Next.js for SSR

Backend: Node.js (Express/Nest.js) or Django/FastAPI

Database: MySQL/PostgreSQL (preferred for scalability) or MongoDB

Hosting: AWS / Vercel / Netlify (open to discussion)

Payments: Razorpay, Stripe, PayPal (custom integration, not plugins)

What I Provide:

A basic React + Vite project (UI skeleton already set up)

Product categories and flow references (I am already a seller on Amazon & Meesho, so I know customer expectations)

Guidance on functionality & user journey

Expectations from Freelancer:

Must code core functionality instead of relying on ready APIs wherever possible

Build a scalable, modular architecture (ready for expansion)

Deliver MVP first, then iterate

Provide documentation + complete code handover

Assist with deployment & debugging

Budget & Timeline:

Budget: Open to proposals (looking for the best balance of quality & cost)

Timeline: MVP in 4–6 weeks, advanced features in further milestones

In short: We want to create an independent, powerful e-commerce ecosystem — drawing inspiration from Flipkart, Shopify, Amazon, and Alibaba, but built with maximum in-house functionality and minimum outsourced dependencies.

This posting positions your project as serious, large-scale, and ownership-driven. It will filter out "template sellers" and attract real full-stack developers who can build core systems.
