Art Castillo

Front-end developer and graphic designer with a systems-first approach to building interfaces that actually work. I design and build simultaneously, which means what I hand off is already thought through visually and technically. Comfortable across the full stack but strongest in React, Next.js, TypeScript, and Tailwind on the frontend. On the design side I work in brand identity, UI, and digital art direction. I’ve shipped production apps, built complete design systems from scratch, and written about technology and systems thinking for an audience of thousands. I work independently by default. No hand-holding needed. Just clear scope and room to execute.
