Jobs end. The way you did them follows you to the next one and the one after that.

Every role finishes eventually, and what continues is your habits and the impression left on the people who worked beside you. Industries turn out to be much smaller than they look from outside. Somebody who saw how you handled your last two weeks turns up on a hiring panel a few years later.

Do the end of anything as carefully as you did the beginning. Leave whatever you built in a state somebody else can pick up. It costs a little and it travels with you.
