Senior product designer, ex-dev.
Design systems, UI, prototypes. Building with AI, shipping to production.

6 years designing complex products, from startups to scale-ups. Now leading design systems at Phrase and impacting teams at

What I do

I own the design system that teams and AI agents build with, and the product work that ships on top of it.

At Phrase, I lead Syntax. PMs and coding agents now build on-brand UI by default, and the system is the base for product redesigns like the most-visited page in the product. When capacity gets cut, I find ways to make the work cheaper to ship.

How I do it

I work systemically and pragmatically, combining product thinking, system governance, and hands-on technical fluency.

I prototype in code, contribute to the codebase when it helps, and work side by side with engineers to make sure systems hold up under real-world constraints. My focus spans interaction design, motion, token-based architecture, and the patterns AI features increasingly depend on.
