Android App Modding Specialists Needed

I have an existing Android APK that I’d like to customize and improve. The job is entirely about modding: de-compiling, adjusting the code or resources, then re-compiling and signing a clean, working build that can be installed right away... (Budget: ₹37500 - ₹75000 INR, Jobs: Android, Android App Development, Android Studio, App Design, Java, Mobile App Development, Software Development, XML)
