SULLIVAN

Hey there — I'm Finn, and I enjoy building projects and systems with AI. I recently finished my undergrad at UC San Diego, where I studied Cognitive Science with a specialization in Design & Interaction. Outside of Claude-maxxing, you'll find me playing guitar or staying active. Interested in my projects, or just want to reach out? Shoot me an email — linked below.

I'm a designer based in San Diego. I recently finished my degree in Cognitive Science with a specialization in Design and Human-Computer Interaction at UC San Diego.

I work best at the intersection of design systems, interaction design, and technical implementation — building things that function as well as they look.
