How do you guys keep different versions of your resumes and keep them updated?

I've read that it is useful to tailor resumes to job applications, also I recently spent a lot of time updating my resume.

That made me think to try to build a tool to make updating resumes less time-consuming, with the design of the resume already taken care of, where you can create "branches" from resumes to tailor specifically for a position/area I just don't know if that would be something useful or if there is already something to do it.

I know people usually make a resume in LaTeX and commit it to a git repository, but seems like a massive time investment to learn LaTeX just to make a resume there.
