Modifying an iOS game app to use custom servers without the app source code

I am looking for a skilled developer to modify a iOS game app, Mini Militia, to integrate custom server capabilities to one of its older versions which no longer has servers supported/online. Specific modifications required: - Integrate custom servers into the old version (version 4.3.2) of the game to allow multiplayer again Server setup: - I am not sure if I need a custom server or if my existing server can be used for this modification such as simply redirecting or changing the domain API. I am open to advice from the developer on this matter. Ideal skills and experience: - Strong knowledge and experience in iOS app development - Proficiency in integrating custom servers into iOS games - Ability to provide guidance and advice on server setup for the modification - Proficient in reverse engineering (game source code is not provided!) Game Frameworks: The game uses an older game engine called Cocos2d-x, we write in C++ for the client, and several other languages for some of the servers too.** IDEs: Xcode, Android Studio, Visual Studio Graphics: Inkscape, GIMP Audio: Audacity Maps: Tiled Frameworks/game engine: Cocos2d-x Languages: C++, C#,, Objective C, Dalvek/Android Application Framework, SQL (that's just for the clients and server, we have other code we use to get things done operations wise), Powershell, Python, etc. If you have the necessary skills and experience, and can provide guidance on server setup, please reach out to discuss the project further.
