Mobile and Web Music Streaming App (Flutter and Django)

I'm after an experienced Flutter and Django developer to work on my project which is currently active and was done by a previous developer but the previous developer did not meet our expectations.

As the project is centered around music streaming, having prior experience in this domain will be a huge plus. Being experienced in working with cloud servers is a must.

The project is currently live and can be accessed through the below:
Web: https://plusliberia.com/
Playstore: https://play.google.com/store/apps/details?id=com.liberia.plus_liberia&hl=en_IN
Apple Store: https://apps.apple.com/us/app/plus-liberia/id6451109693

We need to migrate the site from a share hosting server to a DreamHost Cloud Server and need to fix the below error:
* Change the Music Player
* Improve the app/website speed
* Fix downloaded song error
* Fix the music player when the phone is locked
* Payment gateway issue
* Add artist information on artist page
* Give report on streams
* Give report on download
and few other


Ideal skills and experience include:

- Extensive experience with Flutter and Django
- Prior experience in music streaming app development
- Familiarity with user authentication processes
- Proficiency in managing cloud servers
- Track record of developing mobile and web applications for music
