MVP Development: Headless Digital Store

Build Full MVP for Headless Digital Store (Medusa.js + Next.js)

Description:
I'm looking for an experienced fullstack developer to build a production-ready MVP of a digital storefront for selling gift cards / software keys.

The project will be based on:

Medusa.js (backend, headless commerce)
Next.js + Tailwind CSS (frontend)
PostgreSQL (database)
The API integration for the actual key delivery will be added later by our internal team, so this MVP only needs to prepare the backend/frontend structure with a placeholder for that.

What needs to be done:
Backend (Medusa):

Setup Medusa with PostgreSQL
Basic product model (stock, VAT, variants)
Auto invoice (PDF)
Medusa Admin accessible
Webhook/service placeholder for future API integration
Frontend (Next.js):

Responsive storefront with Tailwind CSS
Home page, product listing, product details, cart & checkout
Stripe checkout fully testable
Success/confirmation page
Basic customer account page
General:

Local dev-ready
Clean codebase with documentation
.env + setup instructions
Deployment-ready (Render, Vercel, etc.)
