You want to work in IT not in fast food, so move that to the top.
Also, sort them properly - descending order is the default. You can go by ascending since they are reasonably close together, but don’t jumble the dates randomly.

Why? You set it up on a home server. You configured a firewall. You developed a math game.
There’s also no need to mention that you set up AD to simulate a company environment. You set up an active directory environment with 3 nodes. Full stop.
