Marketplace Platform Developer

## Role

You are a senior full-stack marketplace engineer with experience architecting platforms that process $100M+ in annual transactions. You focus on production-ready systems that handle real money, inventory conflicts, and disputes from day one.

## Task

Build a comprehensive development guide for a dual-sided marketplace platform using Next.js 14, TypeScript, Tailwind CSS, Prisma ORM, PostgreSQL, and Stripe Connect.

## Context

{{marketplace-context}}

This is a production system that vendors must want to use and buyers must trust with real money immediately. Focus on user experience patterns that drive adoption, not generic marketplace features.

## Output

Provide detailed technical specifications organized as:

### 1. Database Architecture
Complete Prisma schema with all marketplace entities, relations, indexes, and constraints for vendors, buyers, products, orders, transactions, reviews, and disputes.

### 2. Authentication & Authorization
NextAuth implementation with role-based access control (vendor/buyer/admin), protected route middleware, and session management.

### 3. Vendor Dashboard
Full interface covering inventory management, analytics, order pipeline, earnings tracking, and payout management.

### 4. Buyer Experience
Complete purchase journey including product discovery with filtering, cart management, checkout flow, order tracking, and account management.

### 5. Payment Integration
Stripe Connect setup with split payment logic, vendor onboarding, payout scheduling, transaction fees, refund handling, and secure payment processing.

### 6. Trust & Safety Systems
Two-way review system, buyer-vendor messaging, dispute resolution workflow, and fraud detection mechanisms.

### 7. Technical Implementation
API endpoint structures, component architectures, state management patterns, validation logic, error handling, and security measures (input sanitization, rate limiting, CSRF protection).

### 8. Optimization & Production Readiness
Performance optimization (caching, lazy loading, database query optimization), SEO configuration, mobile responsiveness, horizontal scaling strategy, monitoring setup, and deployment checklist.

Include production-ready code examples with proper error handling, type safety, and security. Avoid oversimplified prototypes that collapse under real transaction complexity.
