Xamarin iOS Consulting/Troubleshooting - Multi Threading

We are having some threading issues with our Xamarin iOS application and need expert guidance on how to resolve issues with it. The application communicates with an industrial device via Bluetooth and fills the UI with pertinent information. The BT sensor is constantly being polled for new information which eventually makes its way to the view. We believe there is some cross-threading happening but have not been able to fully resolve it with intermittent behavior.

This project will involve the consultant reviewing the code and architecture of the program with our in-house developer and coordinating the best way to solve it. The ideal candidate will have built many multi-threaded applications in Xamarin targeting iOS.
