innovatewithkishlay/SastaPainter2.0 ? reverse-engineered prompt

Build me a full web app for a painting service business called Sasta Painter 2.0, where customers can sign up, log in, and book painting services or request a site visit. I want a clean customer side and a separate admin side with role based access, so users only see their own booking flow and admins can manage users, bookings, painters, and basic business stats from one dashboard.

Make it feel like a real service platform, with secure login using JWT and Google login too. The frontend should be modern and simple, using React with a nice responsive design, and the backend should handle auth, bookings, and admin actions with Node, Express, and MongoDB. Please set it up so I can run the client and backend locally, and include whatever environment config is needed. If you need to check current docs or best practices for any libraries, go ahead and look them up online.
