Senior frontend engineer — design systems & product UI
I build the component libraries and design-token systems product teams ship on — and the products on top of them. At Autodesk I led the migration of a ~60-family component library to a new design-system generation, with every existing theme kept byte-identical. At Artificial Labs I led Contract Builder, which now drives most of the company's revenue. I also build fullstack products end to end (NestJS, PostgreSQL, Turborepo) and maintain Chunks UI, an open-source React component library.
Led the migration of a shared React component library (~60 component families used across enterprise construction products) to a new design-system generation,
keeping existing themes byte-identical in every migration wave.
