The client is looking for someone to develop an android or react native, Youtube Foreground Player App, similar to mixer box. They need someone with good knowledge of the Youtube API is necessary.
We have pretty well experience using YouTube API, for one private Android app used within a closed group. We listed and played YouTube videos for a specific channel (created by the group). And in one another app, used YouTube API for playing videos in an embedded YouTube video player.
We have been developing Android apps for the last 6 plus years and have command over integrating third-party APIs. Also, we have good experience in the Php language, hence we can create web services/APIs as per the requirement.
We take one project at a time and recently, we have completed an education-based Android Native app. Prior to that, we worked on GPS based hunting app.
