About this gig

Is your Flutter app's video or voice calling feature broken, laggy, or not connecting? I fix Agora, LiveKit, and custom WebRTC integrations fast so you can ship without delays.

What I fix:

  • Audio/video not connecting or dropping mid-call
  • Token/authentication errors (Agora, LiveKit, custom signaling servers)
  • Echo, lag, or poor audio quality issues
  • Android/iOS platform-specific crashes (permissions, native channel errors)
  • Custom native SDK integration via Kotlin MethodChannel/EventChannel bridges
  • Firebase/Firestore real-time sync issues tied to call state
  • State management bugs (Riverpod) causing UI/call desync

Why work with me:

I've built voice/video calling apps from scratch a Clubhouse-style voice room app (Agora + LiveKit + custom native SDK bridge) and a group video party app (Agora + Firebase). I don't just patch symptoms I understand the full RTC stack (client SDK, signaling, token servers, native platform layer), so I find the real root cause.

How it works:

  1. Send me your error logs, screen recording, or repo access
  2. I diagnose the issue and give you a clear fix estimate (time + scope)
  3. I fix it, test on real devices, and hand back working code with a short explanation of what caus
