I need a back end developer for a chat application

I need someone with a deep understanding of WhatsApp's logic. I have made a chat application like whatsapp. Some key features include:

1. Phonebook integration. - All registered users that are on my phonebook will show as contacts on my app.

2. Works offline and does not store messages/media on our server side. Messages/media are stored on the user's phones.

3. has all the bells and whistles whatsapp does except for voice and video calls.

I've tried to implement these features, however I am experiencing trouble such as:

1. Some of the registered users are not showing up on my app

2. Chats don't perform very well, they take forever to send and be received. And I have problems using the same 'storing on the phone' logic whatsapp uses.

Квалификация: Android, Mobile App Development, iPhone, PHP, Java
