React native app

Hi. I have react native app, I need to build apk and ios and submit to stores. Before it, I need to check the apk with social login. I can provide source code, then you have to build apk and test all with social login works, and send me the apk. If all good, we can submit to stores. Budget is small now, but we need to update app after submit to stores. First goal is to publish the app to stores. Thanks
