I run two companies: one builds software for commercial real-estate lenders, the other builds the UI components underneath it. I've been a software engineer, investment banker in derivatives trading (Deutsche Bank and Merrill Lynch), and a real-estate developer.
Chameleon UI by Materia Technologies is a library of Material 3 Expressive web components for Web/JS, React, Blazor, Angular, Vue, and Svelte. One seed color, or an image, generates a full theme. Corner shapes work in every browser (and that means squircles!), and every component targets WCAG 2.2 AA. The Community tier gives you 15 components free for commercial use, and a docs MCP server serves the docs to your AI coding tools.
Chameleon grew out of Dioptra, my loan-portfolio analytics platform. Dioptra needed a serious UI, which led me to co-create Material.Blazor and then Chameleon UI.
