Android Reverse Engineer Need CPP/CS/JAVA

This game is currently on version 4.9.2.
The previous version 3.4.12 uses InjectFix, a hotfix solution developed by Tencent, to load patches on runtime.
Version 4.9.2 abandoned InjectFix.
https://github.com/cc004/BCRInjector/tree/autoub
This tool was created with InjectFix to call certain game API for version 3.4.12.
The main functionality's script where we call those APIs is under \Assembly-CSharp\Elements\
Version 4.9.2 seems (not 100% sure) to use a hotfix solution by Unity to load script: https://docs.unity3d.com/2019.1/Documentation/Manual/android-AppPatching.html
I am looking for someone to bring the functionality of the tool we created with InjectFix for version 3.4.12 back to 4.9.2 either through unity's original method or FakerAndroid: https://github.com/Efaker/FakerAndroid
FakerAndroid translate a apk file to stantard android project include so hook api and il2cpp c++ scaffolding when apk is a unity il2cpp game.
So I am looking for someone who can do CPP/JAVA/CSHARP.
