Real-time Multiplayer Card Game Development

I'm looking for a mobile-only card game developed for both iOS and Android. The complete UI will be provided, so only development is needed.

Key Requirements:
- Implement real-time card game mechanics
- Develop online multiplayer functionality
- Integrate social features such as:
- Friend lists and the ability to invite friends
- In-game chat
- Sharing game results on social media

Ideal Skills and Experience:
- Proficiency in mobile game development, specifically for iOS and Android
- Extensive experience with developing real-time, online multiplayer games
- Skills in integrating social features into games
- Knowledge of card game mechanics would be a plus, however I can explain the logics

I am looking for someone who can deliver a quality product, on time. Good communication skills and a willingness to collaborate are essential.
Developers from Pakistan could get an opportunity to work on this project for a longer term
