Flutter + Agora Expert Needed to Fix Live Voice App (Critical Issues)

We are building a live voice social app (similar to Yalla / Clubhouse) using Flutter and Agora. We are facing critical core system issues and need an expert developer to fix them properly. Main issues: - Mic disconnects when navigating inside the app - Users can sometimes be heard without activating mic (serious bug) - Audio publishing is unstable - RTC session is not persistent - Invitation system is incorrect (needs lightweight inline logic) - Random mic drops and state issues - Chat/text sometimes stops working Requirements: - Strong experience with Agora RTC (must) - Experience building real-time voice/chat apps - Strong understanding of state management and socket handling - Ability to debug and fix core system issues (not UI) Important: - This is NOT a UI job - This is a deep system-level debugging task - We need someone who can identify root causes and fix them properly Please include: - Previous apps using Agora - Explanation of how you would approach fixing mic/RTC issues - Any similar debugging experience We will test you with a small issue before full hire.
