Android App data retrive

I'm looking for a skilled Android developer to create a social networking mobile app. The core functionalities of the app will include:

- User Profiles: Each user should be able to create and customize their own profile.
- Messaging: The app should have a robust messaging system, capable of supporting text, voice, and video messages.

Ideal candidates will have previous experience in developing similar applications, with a strong understanding of Android development. Proficiency in implementing secure and efficient messaging systems is a must.
