Fix SafarSaathi Firebase and Android APK

Full Stack Fix: Real SMS OTP, 0.0ms Live Sync (Driver-Passenger-Admin) & Android APK Hi, I have the complete frontend UI and codebase ready for my ride-hailing & carpooling platform (SafarSaathi), but currently the real-time backend connection is not fully working. I need an experienced full-stack developer to connect everything properly and fix all bugs. Problems to Fix: 1. Real Mobile OTP Not Arriving: Setup Firebase Phone Authentication properly with authorized domain and SMS gateway so real 6-digit OTP arrives instantly on Indian numbers (+91). 2. 0.0ms Real-Time Sync: Connect Passenger App, Driver Console, and Admin Panel using Firebase Realtime Database with proper read/write rules so driver live location, ride posts, and ₹100 UTR submissions sync instantly without delay. 3. Live Nearby Map Tracking: Fix Leaflet/GPS live geolocation so nearby active e-rickshaws show up live on the passenger radar map. 4. Complete Testing & Bug Fixing: Ensure end-to-end flow works flawlessly (Registration -> Live Selfie -> ₹100 UTR Verification -> Admin Approval -> Ride Booking). 5. Android APK Build: Compile, sign, and deliver a clean, working Android APK (Package: com.safarsaathi.app) ready for phone installation and testing. All source code and configs are ready in a ZIP file. Budget: ₹2,000 - ₹3,000 (Fixed Price) Timeline: 24 - 48 Hours Only serious Indian developers who can test on real Indian mobile numbers and deliver a 100% working app should bid.
