Good day. A typical client-server application. I am just finishing up with an application with similar functionality, only without chat. I haven't worked with calls, but I have encountered them indirectly. You can see examples of my work in the portfolio, and I can show some during a personal conversation: not all of them are published on the market, and some I don't know under which package they are published.
Rate $17
