Recover and Verify Mobile Application Code

Hello,
I need an experienced developer to help me recover and verify the source code of my mobile application, Recently, I hired a developer to build the app, but he has stopped responding. I have:

1. A source code file (sent by the previous developer).


2. The APK file of the application (currently installed on my mobile device).



I need someone to:

Verify if the source code matches the APK file.

Rebuild the app if necessary using the existing APK and source code.

Ensure the app can be further developed and maintained.


Skills required:

Mobile app development (Android, iOS).

Source code verification and reverse engineering.

Familiarity with APK decompilation (if needed).


This project is urgent, and I’m looking for a skilled professional who can assist me ASAP. If you have experience in recovering and fixing applications, please send your proposal with your past work experience and estimated timeline for this task.

Thank you,
