I am a new developer.

I'm a new developer.
So I joined Upwork as a freelancer to improve my coding skills.
For a few months now, I've been sending proposals to clients to do some work.
But Nobody send me their reply.
Often, a customer will ask me to give them a call.
But I can't do it because of my personal problem.
So I hope to your help.
Please give me your project so that I can work.
Thank you for you attention.
