Business Database & Streaming Apps

I need a complete back-end and mobile solution that does three things:

1. Build a comprehensive business database that covers retail, service-based, and manufacturing companies—essentially every type of business. Instead of manual entry, the data should be pre-populated by pulling from the Geoapify API, so a solid grasp of their endpoints, rate limits, and best practices is essential.

2. Configure the business flow so users can move seamlessly from customer registration and login through order management and payment processing. Each of those stages must be fully functional, with secure data handling and clear, testable endpoints. The flow also needs to support video recordings that can later be surfaced inside the apps.

3. Extend our existing iOS live-streaming experience to Android. The Android build has to mirror the iOS feature set: real-time streaming, chat overlay, playback of saved streams, and access to the newly created business database. I expect parity in UI/UX, smooth adaptive streaming, and efficient battery/data usage.

Deliverables
• Cloud-hosted business database pre-filled via Geoapify
• API layer exposing registration, orders, payments, video recording links
• Android app matching current iOS live-streaming functionality
• Source code, build instructions, and brief technical documentation

Acceptance criteria
• Geoapify sync completes without data loss or duplication
• Registration → payment flow passes end-to-end tests
• Live stream holds stable for 30+ minutes on standard 4G
• Playbacks and recordings are accessible within 10 seconds of session end

If you have proven experience with Geoapify, real-time video (WebRTC, HLS, or similar), and cross-platform mobile builds, I’d like to see examples when you submit your proposal.
