As a seasoned game developer with more than a decade of experience, I can guarantee that your project is in safe and capable hands. I specialize in Unity game development, including multiplayer functionalities. My proficiency extends to various platforms, such as PC, WebGL, Android, iOS, PlayStation, and Xbox.
I have developed games with complex features like the one you've described and upheld their performance through Unity's Netcode, Photon, Socket, Mirror, Nakama Server and SmartFoxServer. Rest assured that your Ludo and Rummy apps will be fully functional, tested and compatible for both Android and iOS platforms.
What further distinguishes me from the mass is my adeptness in 3D modeling, animation and rigging. With this skill set at my disposal, it'll be seamless for me to not only create the Ludo and Rummy apps but also enhance them using high poly modeling or optimizing low poly models if necessary. Moreover, I'll willingly provide the source code as well as proper documentation for your server storage or maintenance. Let's establish a partnership and evoke something unprecedented in the gaming world together.
