Build DayCaryo Firebase Backend

DayCaryo already has its mobile screens laid out in Figma and the admin dashboard front-end coded; what it lacks is a production-ready backend. I’ve chosen Firebase as the architecture, so you’ll set up Authentication, Firestore, and Cloud Functions (or the REST API gateway) that tie the mobile app and dashboard together.

The platform must handle user authentication, data storage and retrieval, and real-time updates for bookings, caregiver availability, and chat. On top of that, I need seamless integration with a payment gateway (Stripe is my first choice, but I’m open), email/SMS notifications for confirmations and reminders, and Google Maps API so parents can see nearby caregivers and travel estimates.

Please design the data model with future scale in mind, apply role-based security rules, and write well-documented code I can drop straight into my Git repo. A short hand-off call or video walkthrough at the end will help me understand deployment and basic maintenance.

Deliverables
• Firebase project configured (Auth, Firestore, Functions, Storage)
• Secure, documented endpoints for mobile app and admin dashboard
• Payment, notification, and Google Maps integrations wired up and tested
• README covering environment setup, deployment steps, and API examples
