  Looks nice from the landing page, but maybe a bit image-
  heavy for a resume isn't it?

Traditionally, yes. But the point of a resume is to get the phone screen. If images and formatting will pop for Company X, go for it.

  Just make like an HTML page with every possible detail 
  about your history. Then, in e.g. Chrome, you can 
  easily hide the different sections/words that isn't 
  related to the specific job you're applying for.

Awesome idea. I re-write my resume for every job opening. All the way down to nouns and buzzwords associated with that particular company. Hell, I've gone so far as to subtly match their branding (e.g., fonts, text treatment).

It strikes me as really hard to do that programmatically without a mess of show/hide logic that defeats the point.
