I care about the half-second between click and response.
Five years building interfaces for design tools, developer platforms, and data-heavy products. I work close to the design side — type, spacing, motion — and close to the metal — bundle budgets, render profiles, accessibility trees.
Currently a senior frontend engineer at an enterprise software engineering and AI agency. Before that: agency work, a stint in data visualisation, and one very long year maintaining a component library used by ten engineers.
