About this gig
Are you looking to build a high-performance video/audio calling app or real-time streaming platform? I specialize in engineering cross-platform mobile applications using Flutter, WebRTC, and scalable backends (Supabase / Firebase).
From custom UI/UX mockups to production-ready video calling apps with low latency, I deliver fast, 60 FPS media experiences across Android and iOS.
What I Offer:
- Basic Package ($150): Complete multi-screen responsive Flutter UI design, custom video/audio call interface, and state management setup.
- Standard Package ($600): Full UI design + Firebase/Supabase user authentication, real-time 1-on-1 text chat, and push notifications.
- Premium Package ($1,500): Turnkey WebRTC video/audio calling app with signaling server integration, auth, chat, screen sharing, and support system.
Technical Capabilities:
- Peer-to-Peer (P2P) WebRTC real-time media streams
- Low latency audio/video synchronization & adaptive bitrate handling
- In-app call controls (camera toggle, mic mute, screen share)
- Clean, scalable, and fully refactored Dart code
Please send me a message before placing an order to discuss your exact project scope and backend setup!

FAQ
Do you support WebRTC SFU/MCU setups or third-party engines like Agora/LiveKit?
Yes! I can build native WebRTC solutions using custom signaling servers or integrate third-party platforms like Agora, LiveKit, and ZEGOCLOUD based on your scalability needs.
Can you handle the backend signaling and database configuration?
Yes, I set up backend connections using Firebase, Supabase, or custom Node.js signaling servers to ensure secure SDP/ICE candidate exchanges.
