I'd happily submit my CV as json... :)

That’s the thing, in general you are not chosen by the relevance of your resume. Resume building is more SEO than showcasing relevant skills. If you can min max your SEO to get a conversation with someone who matters in your hiring process, then it works.

That sounds like a great way to show off your skills in over-engineering and tightening screws with a hammer.

More to IT then web apps... (to mis-quote Ross from Friends, Front OR Back :P)

Yeah sorry, none of this is a good idea. If you are in marketing or something like that it may benefit you to get a little creative with resume formatting, but even that has limits. Stick to PDF resumes if you must do something fancy like that include it as a link to your resume. When I have 20-200 resume's to sift through the fact that I have to somehow store a link to your resume, while everyone else's is a PDF in folder that I can easily peruse at any time will work against you, not for you.

As a front end designer, you should understand, fancy and flashy is not the same thing as good UX. When I have to compare a bunch of candidates a predictable format is far better UX than whatever "creative" way you've chosen to try to demonstrate your skills, and what you've really demonstrated to me is you've failed to consider the needs of your user.

Edit: This should have gone on the GP's comment, but applies here too.
