I’m building a cross-platform marketplace that lets property owners list rentals and lets seekers find their next home. The app must be written in Flutter and backed by Firebase (Authentication, Firestore, Storage) so we can launch simultaneously on iOS and Android. Core workflow • Users sign up or log in, then land on a profile that adapts to their role—owner or seeker. • Owners create listings with descriptions and a set of photos stored in Firebase Storage. • Seekers browse listings and refine results by location, price, and number of bedrooms. • Anyone can tap the heart icon to save favourites. • Secure in-app messaging connects seekers with owners without exposing personal details. I need you to take the project from blank repo to store-ready release, covering UI/UX design, Flutter development, Firebase setup, testing, and deployment support. When you respond, please tell me: 1. How many years you’ve worked with Flutter/Firebase and which versions you’re most comfortable with. 2. Links or screenshots of similar marketplace or real-estate apps you’ve shipped. 3. A clear timeline with milestones and an estimated cost. 4. A portfolio or GitHub profile I can review. Deliverables at hand-off 1. Clean, well-commented Flutter source code. 2. Configured Firebase project and security rules. 3. Tested builds ready for TestFlight and Google Play internal testing. 4. Short deployment guide so my team can maintain and scale the app. I’m ready to start as soon as I find the right partner and will be actively available to answer questions, review work, and sign off on each milestone.
