React native expert


Hi, I have a react native project and but there are some issues.

I've implemented Google Signin by using firebase and getting DEVELOPER_ERROR.

I know its related to SHA1 code for keystore.

But I have tried many times and it didn't work.

I need an expert to fix this issue quickly.

Its long term position and after fixing it, I will give you more tasks in this task.

Btw, it should be done via remote.

If you don't agree, then don't apply.

Please place a bid if you are expert.
