Dear Ashmit5ingh,
It's great to hear about your vision for a multi-tenant car dealership auction platform, "Develop React/FastAPI Car Dealership Auction Site." I understand your need for a robust, scalable solution with live auctions, integrated CRM, and secure billing.
My name is Navneet, and I've spent the last [Number] years building high-performance SaaS applications and auction platforms, specializing in React, FastAPI, and PostgreSQL/Redis architectures. I have a proven track record of delivering secure, scalable multi-tenant systems with integrated 3rd-party APIs.
My approach would leverage a microservices architecture for scalability, building out the core auction engine with Redis for real-time bidding and PostgreSQL for data persistence. The frontend will be developed using React for a smooth user experience, and FastAPI will power the robust, secure APIs.
I'm confident I can deliver a fully functional MVP meeting all your requirements, including your desired features like KYC, RBAC, and a comprehensive admin panel.
I'd love to discuss this further and answer any questions you may have.
Sincerely,
Navneet
