I love the site too.
It is built on Gatsby static webpage generator and is very fast, gets about 98-100 for desktop on Lighthouse (or Pagespeed Insights) despite looking content heavy. It has dark mode toggle button, nice font and stylishly simple.
Also, she delivers amazing tutorials on hot coding topics for free.

Thanks, you reminded me I read Steve Krug's Don't Make Me Think, Revisited (2014) recently and decided a lot had to change with my site! Excellent book.
