I’m facing a critical issue in my Flutter application and I’m looking for an experienced WebRTC developer to help me resolve it. Project Overview: Mobile App: Flutter Backend: Node.js Real-time Communication: WebRTC + [login to view URL] TURN Server: Hosted on my own VPS App Type: Calling & Chatting App Problem Description: Calling works perfectly when both devices are connected to the same WiFi/network. When devices are on different networks, the call does not connect initially. If the receiver calls back, then the connection succeeds. After this first successful call, both users can call each other normally, even on different networks. I have tested with a [login to view URL] TURN server, but the issue still persists. What I Need: I want to identify the root cause of this issue (ICE candidates, TURN/STUN configuration, signaling, SDP handling, NAT traversal, etc.) and apply a proper permanent fix. Requirements: Strong experience with WebRTC Experience with Flutter WebRTC Knowledge of TURN/STUN servers Familiarity with [login to view URL] signaling Ability to debug real-time communication issues If you have faced and solved similar WebRTC network-related issues before, please contact me with your experience and approach.

I viewed your project and am confident I can deliver what you need, prioritizing clean, maintainable, and real-world outcomes. I'm currently working on a similar project and understand how ICE timing issues, NAT traversal gaps, and SDP signaling flaws cause first call failures across networks, I will identify and permanently fix candidate exchange, TURN usage, and connection sequencing, since you need timely, accurate insights for decisions, how often do you want connection state diagnostics refreshed during testing? I invite you to view my portfolio, which showcases the quality and results of my past work. I'm looking forward to your message so we can align on the specific features and immediately define the next steps! Regards, Sadiya
