Make updates to React Native Project and deploy app

I’m looking for a developer to make updates my app.
The code base is dated, so It may need to be updated as time goes on.
The live apps can be found here: https://play.google.com/store/apps/details?id=com.ch_music&hl=en_US&gl=US
and

Please be well verse in earlier versions of React Native and Firebase.

At the top of your bid, please put “I know old and new” so I can filter out auto bids.
