Messaging App Development

I'm in need of a skilled app developer who can help me create a private messaging app. Core features should revolve around enabling users to interact through private messaging.

Here are some details on what I'm looking for:

- Private Messaging feature: Users should be able to initiate and sustain individual conversations in a private and secure manner
- Integration: The app doesn’t need to integrate with any existing platforms, so the focus will be on the standalone functions.

Ideal skills and experience:

- Proven experience with app development, specifically in creating messaging apps
- Excellent understanding of privacy and security protocols to ensure secure private messaging.
