Senior Developer for Messenger Project / ejabberd / XMPP wanted

Hi nice to meet you here,

we are looking for a very skilled and experienced developer in a long term partnership.

We are in the process of building a HTML5 based Chat App like WhatsApp - with all possibilities WhatsApp provides. (text chat, push notifications, sending pictures, etc, audio call, video call, etc.)

The "App" needs to work on Desktop and Smartphones. Fully HTML5 based (NO native App please, we want to avoid App stores) with push notifications using PWA technology on Smartphones. The frontend Design is almost finished in html5 / css by our own designers

(see attached pdf).

We want to build a very robust, highly scalable system in the backend which can handle large scale traffic and a big number of users simulatiously. So we prefer using the ejabberd Server / XMPP.

If you have a long term experience in building up applications like described, please send me a quick answer, so we can setup a call and discuss the project. please send a message only if you did applications like that before successfully and can show the whole app running or parts of it.

if we match, we can start the project right away...

thanks from Berlin

christoph
