i need Developer to integrate Google's Exoplayer

I need an Ionic Android developer with experience of Google’s Exoplayer. I already have an application called Altrahd ( which contains 30sec short videos) , I just need replace existing media player with Exoployer. currently we have so much of buffering the video with existing media player. So with Exoployer we can get smooth playback and reduce null buffering. Addionally need to fix 3 to 4 bugs and admob ads new placements needed.
