Game Developer - iOS/Android

I'm seeking a proficient game developer to craft a moderate complexity action game for iOS and Android platforms. My vision for the game includes some special features:

- Multiplayer Capabilities
- In-App Purchases:
- Leaderboards or Achievement System:

Ideal developers should have a proven track record in action game development, working knowledge of multiplayer systems, in-app purchase monetization strategies, and implementation of leaderboard or achievement systems.

****
Must have experience with in-app purchases, connecting Admob, working with Firebase, Experience working in App store connect and submitting apps for approval in the App store. You or your team. We would like to work with someone who would like to grow with us not just a short term project but a long-lasting relationship.

Please include examples of games or apps you have developed currently in the app store, I'd like to see both successful and not so successful projects. I understand not everything is going to be a hit. I want to understand both sides.

Also we work in the day time USA hours. Someone would need to be around our time to communicate. Please let us know when you work.



Thanks
