This page is based on the React-based NextJS framework. It's design is heavily based on the Geist UI design system. Inspired by Lee Robinson, posts and text-heavy pages (like this one) are written using MDX, a Markdown library for the component era.
On the infrastructure side, the website source code is hosted on Gitlab.com, built with Gitlab CI/CD and finally deployed on Gitlab Pages as a static pre-rendered page. The website is deployed automatically on a daily schedule to allow for data snapshots like the TickTick page.
