I built something similar a couple of years back when I was job hunting using a json and Angular.js, I called it modern resume [1]. Live example can be found here [2]. I got tired of having a resume for each format - plain text, html (website), word document, PDF. Every change had to be made in all the places. I wanted to have a single source of truth. This kind of standardization would be great!
