Have you looked at JSONResume [0]? I build my resume in JSON and use git and github pages along with the resume-cli [1] to export it out to HTML/PDF formats. My homepage is a single page hosted with github pages that links to these exported resumes and the JSON one too.

Ideally I would like a single CLI command that pushes out my updated resume to all those sites.
