While in undergrad I wrote a modular resume script that picked a set bullet points based on the tags I gave them, rendered those bullets into a LaTeX template, and then spat out the customized result with a PDF. With this I could quickly spin out slightly different resumes that showcase different tech stacks, emphasize/de-emphasize military service or defense contractor work, drop (or add) bullets that imply I was an older-than-usual grad, etc.
I still use the script out of habit, though I wouldn't write it now.
