Integrate Google SignIn for a React Native Expo CLI APP

Project Description:
I am looking for a developer to integrate Google SignIn into my React Native Expo CLI app. The app is targeting both iOS and Android platforms.

Skills and Experience:
- Experience with React Native Expo CLI and React Native development
- Familiarity with Google API credentials and authentication
- Knowledge of setting up necessary packages and dependencies for React Native Expo CLI

Requirements:
- Integrate Google SignIn functionality into the app for both iOS and Android platforms
- Set up the necessary packages and dependencies for React Native Expo CLI, if not already done

Note: The client has existing Google API credentials but may need assistance with setting up the necessary packages and dependencies for React Native Expo CLI.

Warnings:

1. An expo dependency is already deprecated, I will not accept it as a solution
2. Expo useProxy is deprecated as well for security reasons, therefore I will not accept it
3. I need this to be implemented for Android and iOS
4. Budget $40 take it or leave it
5. Please, start your bid with the word: "COFFEE" so I can know that you are not a bot and that you have read the description
