Oops! All Ragtime!

I was trying to solve a problem, as you do. My effort to make an LLM-powered job and resume management system, I realized that I needed to be able to pull apart a job description, figure out what it was really asking for, then match that somehow against a scattered career history to figure out what parts of my unique background were actually relevant to that specific job.
