I am super disappointed that jsonresume.org can't fix their formatting issues surrounding output to pdf and ms word. I am not casting stones as the contributors are all a super talented bunch. Coming from the Python/R-project universes and having started up a professional services firm for individuals in Shanghai; English resume editing, interview coaching and LinkedIn Profile creation, I simply don't have the time to learn and modify the underlying node.js code. The ability to easily ingest and store the resumes I am supplied with and then the highly improved product I create would be invaluable. I have learned the hard way how difficult programmatic formatting for the mass market really is. As a professional resume editor, I concur 1) simpler is always better, 2) white space is as important as what is on the printed page, 3) use 1 1/2 to 2 pages for readability. Many resumes are run through ATS parsers/processors and you do not want to use such fancy fonts and styling that you provide any chance for your document to be rejected by the system. There are other tips and tricks but those are the most basic. Great discussion here.
