I figured it was time to free my resume from the clutches of giant corporate software, so I've rewritten it here in HTML. In the past, I've experimented with TeX, Word, Google Docs and probably a few other tools, but I think HTML is the clear winner going forward.
HTML is win. There's no compiling, transpiling or converting to be done. It just works. In every web browser.
First of all, anyone who absolutely requiring DOCX knows exactly where to shove it.
Second, a PDF is easy enough to generate with "Print to PDF" and similar features. Add in a touch of print CSS, and it's golden.
