This website is a perpetual work in progress.
It is running an MIT-licensed content management system called Preaction CMS, and I can update its contents easily from my mobile device. I started working on this in my free time in 2018, and I recently released the version 5 Alpha, which represents the most significant open source project I've worked on to date.
You can learn more about this and other things I may be working on by visiting my portfolio.
