About

I'm a full stack developer who cares deeply about the quality of both the product and the system behind it. I enjoy shaping interfaces, defining technical foundations, and helping teams build things that are clear, reliable, and easy to evolve.

Let's build something clear and well made.

Working on a product, redesign, or technical foundation that needs strong frontend execution? Reach out.
