Android studio code obfuscation -- 2

I am looking for an Android developer who can help me with obfuscating my code in Android Studio. The purpose of the obfuscation is to protect my code from reverse engineering. I am not sure if my app is using any third-party libraries or APIs. As I am not familiar with obfuscation techniques, I need guidance on choosing the best technique for my app. Ideal candidates for this job should have experience in Android Studio and obfuscation techniques.
