Projects like these is exactly what university use for teaching too! You're way ahead of the curve. For example CMU also makes you write your own shell. The main focus is implementing job control like: jobs, fg, bg, and various signal handlers in order to understand how forking child processes work. I see that your shell doesn't handle much other than cd so this might be a nice next step if you want to continue working on it.
