sandhyacs-d/Nestly ? reverse-engineered prompt

Build me a full stack app for finding rentals and roommates in one place. I want people to be able to sign up, create a profile, post a place or a roommate listing, browse available options, and search or filter by things like location, price, and what kind of roommate they want. It should feel simple and modern, with a clean homepage, listing pages, and a basic dashboard where users can manage what they posted and what they saved.

Make the app work end to end, with a smooth front end and a solid back end, and use a common modern web setup if that fits this project. If anything is unclear, make sensible choices and look up current docs online if you need to. Focus on making it usable and polished first, with the main flows working well.
