For a techy person, GitHub pages + markdown is all you need: https://quanticdev.com/articles/website-with-github-pages
When you already know Git & GitHub, you get an all-in-one experience with your code & website side by side.
I'd add to use Jekyll now (https://github.com/barryclark/jekyll-now) for a few more out-of-the box conveniences. Sadly, it's unmaintened, but the it gives a sufficient base as-is.
