Required Tech Stack & Infrastructure Experience: Frontend: Next.js (App Router), TypeScript, Tailwind CSS. Backend & Database: Supabase or similar (PostgreSQL, Row-Level Security, Auth). Hosting & Deployment: Vercel or similar (for lightning-fast global Next.js frontend and serverless function deployment). Cloud Storage & Services: AWS (specifically Amazon S3 or equivalent object storage for handling high-resolution vehicle inspection documents, photos, and forensic PDF reports securely). Payments: Stripe Connect or similar (for multi-party payment splitting and secure transaction processing). AI / RAG Integration: Experience connecting LLM APIs (OpenAI / Anthropic) with vector databases for custom knowledge-base retrieval. Key Features to Build for the MVP: Multi-Tab Marketplace & Smart Search: Clean UI supporting vehicle inventory grids, dynamic filters, and a VIN-based parts compatibility lookup system. Secure Authentication & Roles: Role-based access control (Buyers, Sellers, dealers, and Admins) powered by Supabase or similar Auth. AI Technical Assistant: An embedded RAG-based chatbot interface trained on technical inspection guides and diagnostic manuals. Production Deployment & CI/CD: Seamless environment setup connecting GitHub to Vercel for frontend hosting and AWS/Supabase for backend persistence and storage.

Your Background: Proven portfolio of shipped SaaS platforms or marketplaces with verifiable production links.
