This is pretty cool. From a UX standpoint, my first intuition was to use ls to list out the directories and to use tab to autocomplete, neither of which worked. The animation is cool but it's a little slow and might be frustrating if I was trying to read the resume for real to get info rather than just playing around with the demo.
Still really cool though. I made a prototype resume myself recently[0], great to see more of these creative ways of showing off experience.
