These documents are actually generative. I set up a LaTeX document in overleaf that converts a spreadsheets .csv file to a resume. The design is based off a command template for resume items so changing the template changes the entire thing, for example switching from bold to italic on a line or two page to one page. This system makes my resume extremely adaptable– by simply commenting in/out a few lines of code the format and content can be customized directly to the application at hand.
