nginx proxy requests from SSH to TCP

Question

is nginx capable of such a proxy: user to nginx uses SSH; nginx to backend server uses TCP. So far, I have found a solution like the following, but it is said to only proxy SSH to SSH.

worker_processes 1;
events {
    worker_connections 1024;
}
stream {  
    upstream ssh {
        server 192.168.4.102:80;
    }
    server { 
        listen 80;
        proxy_pass ssh;
        proxy_connect_timeout 1h;
        proxy_timeout 1h;
    }
}
