8-Bit Classic Arcade Game Development

I'm looking for a freelance developer to create a simple, 8-bit style arcade game for Android.
Game Features
Arcade Gameplay: The game should have a simple and engaging core loop, like a classic arcade game.
8-Bit Art Style: The graphics must be in a distinct 8-bit aesthetic.
In-Game Currency: Implement a currency system (e.g., gems, gold, or coins).
In-App Purchases: Users must be able to purchase this in-game currency.
User Login: The game needs a user login system. Google Sign-In is a required feature.
Play Console Integration: The final APK needs to be prepared for upload to my Google Play Console account.
Project Scope
Development: Create a fully functional and tested Android game.
Play Store Submission: The developer will be responsible for uploading the game to my Google Play Console account and managing the submission process to get the game approved and live on the Play Store.

I'm seeking a developer with a strong portfolio in mobile game development, especially with experience in in-app purchases and the Google Play Store submission process. Please provide examples of your previous work and a clear timeline for the project.
