Fbet app continuation

I am looking for a skilled developer to continue working on my Fbet app. The app currently has user profiles and push notifications, but I am looking to add the live betting feature. Specifically, I would like a custom-built betting system that integrates with existing bookmakers and provides real-time odds updates. The ideal platform for this system would be a mobile app. The developer must have experience in mobile app development and expertise in building custom betting systems.
