About

Product-minded, implementation-focused.

I have worked across customer-facing commerce products, internal admin systems, authentication flows, and mobile webviews. I care about making complex states understandable to users and maintainable for the team.

I work closely with product managers, designers, and backend engineers to turn incomplete requirements into clear, shippable interfaces.
