I am wanting a very fast app that can be used on all devices (e.g Computer, Phone, Tablet..) and with ios and android. The app will be exactly like facebook messenger but with added freelancing features. It has to be able to accommodate 10,000 active users at once.
I have already designed it on adobe xd - so I only need you to build it.
I want a freelancer who knows exactly what they are doing and I don't mind how long it takes to build it.
Preferably max 2 months
