I'm a frontend-leaning engineer who treats the interface as a system: tokens, primitives, data flow and build tooling designed together so the product stays fast and consistent as it grows.
Lately: design systems, performance budgets, shipping more HTML with less JavaScript, and working with generative and agentic AI.
