Urgent Mobile App ( React Native + Python ) needed

Hi,

I have wireframes ready..
I need to start urgently to develop this app. I will opt for anyone of these :

1. ) Front end : React native + Back end : Python
2. ) Front end : Flutter / Dart + Back end : Firebase

Only full time ppl, who arent handling any other project need to bid.
As i need this urgently.

Thanks
