How this site was made

  • WhoI designed the site and made each design decision. Claude wrote most of the code with me.
  • HeroMy name is live text. The lens redraws the same letters from data points.
  • Chapter"How I work" is a single scroll-driven scene, and every layer in it is drawn in code.
  • TheseThe glass buttons are rendered with Three.js. Real buttons sit underneath for keyboards and screen readers.

In this view each project card leads with one interface decision I made in it.
