Not OP but I use an iPad occasionally to remote in to a linux box and work on projects. I use blink for the terminal app and connect using mosh instead of ssh.

Not OP but I use an iPad occasionally to remote in to a linux box and work on projects. I use blink for the terminal app and connect using mosh instead of ssh. I found that mosh handles the connection (reconnection) way better since iPadOS is pretty aggressive in killing the terminal app if I switch to a different app. I use also tmux on the server and just detach it when I'm done in case I want to work on it on my laptop or desktop. Overall works great, my only issue is that the 10.9" iPad screen is a _little_ bit too small for my liking so I don't do work like this that much. If I had the 12.9" iPad it would probably be something I use daily.
