I’m a principal design engineer focused on agentic products. I shape how people work with agents and build the interfaces, tools, and backend systems behind those experiences.

today

At Block, I work on agent environments, tools for guiding model behavior, and prototypes that connect generated interfaces to actions. My work spans product exploration, systems architecture, and implementation.

yesterday

At Cash App, I stood up its design systems practice, architecting a code-first system that drives 95% of its surfaces for 60 million users.

about

how I work

I develop ideas through working prototypes and stay involved through production. Depending on the problem, that means tuning a drag interaction, building the backend behind an interface, or designing a system other teams can build on.

For agentic products, I work through when an agent should act, what it’s allowed to do, and how someone can understand and steer the result.

Agents are part of my daily practice. I put care into their context, tools, and constraints, then review the architecture, behavior, and details of what we build. I’m responsible for those decisions and for checking the result.

outside of work

I like building small, powerful computers. I enjoy the challenge of fitting everything into less space and making it beautiful.

I obsess over interior design, take photographs, and climb to blow off steam. I read a lot of science fiction and dabble in writing it.

My partner and I want to buy land with a stream someday.
