You've Found A Secret Page!
In addition to being a voice actor, I am also a web developer.
As such, I have built this website myself.
Rather than using a web builder (such as Squarespace, Wix, Wordpress), I used React.js and Gatsby.js - a frontend framework used by web developers.
While no CSS library was used, as I like my css to be completely custom, I used Scss, a CSS preprocessor was used, in order to nest my CSS - making styling much cleaner.
While this setup seems much more complicated (and definitely is) for anyone first starting to make a website, this allows to do what I love to do with my websites - make absolutely everything custom.
