Hello

I have worked for nearly three years as a software engineer on a SaaS platform, building product features in React and TypeScript and writing the regression, load and canary suites that test them. Before that came five years of frontend and ecommerce work: storefronts and ERP integrations, and agency client sites on most of the site builders.

I also run a small studio, where I design and build client sites and the internal app the studio runs on, and I publish a design system and the tools around it.

haus is the design system everything else here is built on, token-first in OKLCH and published to npm as five packages. drift takes a URL and reports the design system that site actually ships, crawled with Playwright and deduplicated on perceptual colour distance. core is a team decision log with a permission-gated lifecycle and two audit trails, and vault is an offline Mac app for colour and type, Electron over native SQLite. Pendula covers the two test suites I wrote for a customer-engagement platform, BDD regression in Cucumber and canary and load tests in k6.

The small tools are standalone and each one is live on its own domain. They cover CSS parsing, colour science and simulation, and all of them sit on kern, the shared layer underneath. The essays so far cover defaults, naming, motion and colour scales in design systems. Snippets collects the motion and interaction techniques that come out of client work, each one a live demo with the source next to it.
