Build Android Audio Social App with Live Voice Rooms, Coins, Gifts & Games

I am looking for an experienced Android/Flutter developer or small development team to build an Android-first audio social app called VIBORA.

IMPORTANT:
This is NOT a video streaming app. No video calling or video live streaming is required for the MVP.

The app will be an audio social platform where users can join live voice rooms, chat, talk with other users, send virtual gifts, use coins, follow hosts/friends and play games.

I have a detailed Developer Requirement Document and UI reference showing the desired style and functionality.

TECHNICAL REQUIREMENTS:

- Android-first MVP

- PostgreSQL preferred for wallet/financial ledger
- WebSocket for realtime chat/room state
- Agora or LiveKit (or another reliable RTC provider) for live audio
- Cloud storage for profile/room images
- Secure API
- Server-side wallet/coin calculations
- Payment gateway integration with secure server-side webhook verification
- Admin panel using React/Next.js or similar

IMPORTANT SECURITY REQUIREMENTS:

- Coins must be server-side controlled
- Gift transactions must be atomic
- Payment webhooks must be verified
- No client-side wallet manipulation
- Game results must be server-authoritative
- Admin actions must be logged
- Basic anti-fraud protection
- Report/block/moderation system

BUDGET:

Maximum initial MVP budget: ₹50,000 INR.

I understand that third-party services such as RTC/audio, hosting, OTP, payment gateway, cloud storage and app-store fees may have separate costs.

I am NOT asking for a full PartyStar clone at this budget.

I want a clean, working MVP that can later be expanded.

MILESTONE PAYMENT:

Milestone 1:
UI + Login + Home + Profile + basic navigation

Milestone 2:
Live audio rooms + microphone seats + chat + host controls

Milestone 3:
Coins + recharge + gifts + transaction ledger

Milestone 4:
Host wallet + earnings + withdrawal workflow + admin panel

Milestone 5:
Games Center + basic game integrations + testing + bug fixing

I will release payment milestone-by-milestone after testing the delivered functionality.

DEVELOPER REQUIREMENTS:

Please apply only if you have experience with:
- Live audio/voice chat rooms
- Agora/LiveKit/ZEGOCLOUD or similar RTC
- Flutter/Android

The final project must be deployed under accounts owned by me.

Please do not apply if you have never developed a realtime audio room application.
