Anyone using their iPad to program on?

I bought the new iPad Pro to do hand written annotations of my mathematics books, but didn't honestly expect to be productive programming on it. However, I'm still curious if anyone here found a way to program effectively on an iPad? I would imagine a terminal emulator and SFTP/SSH app would be necessary, probably running tmux. However, I'm also interested if anyone here is self hosting a server to ssh into as well perhaps using port forwarding and dynamic dns?
