TCP Tunnel - Reverse Proxy

hello i want to make a project the project will be like ngrok
how will it work ?
will give the user a subdomain and port should give different for each user
and the user will use it on her server or minecraft server, she will be able to listen to the data coming in with an agent or client program.
