B2B Dental Prosthetics Marketplace Platform

# Full-Stack Developer Needed: B2B Dental Prosthetics Marketplace Platform

## Project Overview

We are building **DentalSource**, a B2B marketplace platform connecting dental clinics with dental laboratories for prosthetic manufacturing. Think of it as "Uber for dental prosthetics" – dentists upload cases (3D scans, photos, prescriptions), and qualified labs compete to produce crowns, bridges, implants, and other dental restorations.

**Live Prototype:** https://dentalsource.vercel.app/login
*(You can explore the current UI/UX – the frontend is partially built using v0.dev/AI-assisted coding)*

---

## What Exists Today (Prototype)

The current codebase is a **Next.js 14** application with:
- UI pages and components built with React, Tailwind CSS, and shadcn/ui
- Basic Supabase integration (auth, database schema, storage buckets)
- Partial API routes structure
- Stripe integration scaffolding
- Multi-language support (EN, FR, ES, DE, ZH)
- Role-based navigation (Dentist, Supplier/Lab, Admin)

**However**, most backend logic, business rules, real-time features, and integrations are **incomplete or non-functional**. We need a skilled developer to transform this prototype into a production-ready platform.

## Scope of Work

### 1. User Management & Authentication
- Complete Supabase Auth implementation with magic links and OAuth
- Organization/clinic management (multi-user clinics)
- Role-based access control: **Dentist**, **Supplier (Lab)**, **Admin**
- User onboarding flows with profile completion
- Team invitation system for clinics and labs

### 2. Order Management System (Core Feature)

**For Dentists:**
- Multi-step order creation wizard:
- Patient information input
- Product selection from catalog (crowns, bridges, implants, aligners, etc.)
- Dental chart integration (FDI notation)
- 3D file upload (STL, PLY, ZIP) with viewer
- Photo uploads (intraoral, preparation photos)
- Shade selection, material preferences
- Deadline and priority settings
- Draft order saving and resume
- Order tracking with real-time status updates
- Messaging with assigned lab

**For Suppliers/Labs:**
- Scan inbox for receiving files from dental software (Digilab integration via API)
- Order acceptance/rejection workflow
- Production step tracking (configurable per product)
- Quality control photo uploads
- Shipping management and tracking integration

### 3. Supplier Marketplace & Matching
- Supplier catalog with pricing, materials, certifications
- Automatic or manual supplier matching based on:
- Product type
- Material availability
- Price
- Lead time
- Geographic location
- Quality ratings
- Quote request and comparison system
- Supplier performance analytics

### 4. Billing & Credits System
- Pre-paid credits system for dentists
- Stripe integration (payment intents, webhooks)
- Wire transfer support for EU customers
- Invoice generation
- Credit transaction history
- Organization billing management

### 5. Real-Time Features
- Order status notifications
- In-app messaging between dentist and lab
- Push notifications (optional)
- Real-time dashboard updates

### 6. Admin Panel
- User management
- Catalog management (categories, products, configurations)
- Supplier verification and onboarding
- Dispute resolution system
- Analytics dashboard
- Market test landing page management

### 7. Integrations
- **Digilab API**: Webhook receiver for dental scan software
- **Shipping carriers**: Integration for pickup scheduling and tracking
- **Stripe**: Complete payment flow
- **File storage**: Supabase Storage for STL/3D files, photos

### 8. Technical Requirements
- Production-ready error handling
- Proper database indexing and query optimization
- Row-Level Security (RLS) policies in Supabase
- API rate limiting
- Comprehensive logging
- Unit and integration tests
