Integrate Social Logins & Publish Mobile App

I need a skilled developer to integrate Apple, Google, and Facebook logins into my Flutter app and React.js web frontend. The backend is built with Django API Rest. Additionally, I require assistance with creating new listings on the AppStore and PlayStore for publishing the app.

Key Requirements:
- Implement social logins: Apple, Google, and Facebook
- Create new app listings on AppStore and PlayStore
- Publish the app

Ideal Skills:
- Proficient in Flutter and React.js
- Experienced with Django API Rest
- Familiar with Apple and Google developer accounts and their publishing processes

I already have the necessary developer accounts for both Apple and Google, but I need new app listings on both stores.
