Cross-Platform Booking & Video App

I’m ready to build a marketing-driven mobile application that works seamlessly on both iOS and Android. The core experience revolves around a robust booking calendar where users can register or log in, view available slots, and lock in appointments. To help each service stand out, providers must be able to upload a short thumbnail video that plays smoothly inside the app, giving prospects a quick preview before they commit.

Key flow
• Secure user registration and social login
• Calendar-based booking with real-time availability
• Thumbnail video upload, storage, and in-app playback

Essential integrations
• Payment gateway (Stripe, PayPal, or similar) so clients can pay at checkout
• Two-way sync with external calendars like Google or Outlook to prevent double-booking
• Automated push of all customer and booking data into our existing CRM

Deliverables
1. Production-ready iOS and Android apps (React Native, Flutter, or native—happy to adopt your strongest stack)
2. Back-end/API covering auth, booking logic, video handling, payments, calendar sync, and CRM hooks
3. Lightweight web admin dashboard for managing users, schedules, and video assets
4. Full source code with build instructions and a brief hand-over walkthrough video

The code must be clear and well-documented so my in-house team can maintain it after launch. If you have live examples of similar work or can suggest performance-minded hosting for video assets, that will help us move quickly toward testing and release.
