Here's a few things I've made:

• Compendium of Lesser Hyperlinks, a page with silly UI experiments
• NonEuclid, a Minecraft server plugin for making impossible overlapping pathways
• react-draggable-list, a React component for making reorderable lists
• react-menu-list, a React library for making dropdown menus
• react-multi-ref, a small utility for managing lists of element refs in React
• I write technical blog posts sometimes, but it's been a while.
