umeraslamwattoo/Build-hub ? reverse-engineered prompt

Build me a full stack construction marketplace called BuildHub where clients can post building projects like homes, hospitals, or universities, and builders can browse them, send bids, and negotiate in real time chat.

I want separate logins for clients and builders, profile pages, and dashboards for each role. Clients should be able to create a project with lots of construction details, see an estimated price as they fill it out, view builder profiles and ratings, then accept, reject, or chat about offers. Builders should be able to see open projects, submit their own price and notes, follow active jobs, mark work as complete, and get reviewed when the client approves it.

Please make the app feel polished and easy to use, with notifications, status tracking from pending to complete, image uploads for profiles, and a floating AI helper that can answer general questions. Use the current best practices for the stack and look up any docs online if you need to.
