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

What I do

I design and lead design systems so teams can stop arguing about implementation and focus on real product decisions.

Components, tokens, patterns, and documentation are the foundation. Prototypes, production-ready code, and tight collaboration with engineering are how it actually ships. My work supports dozens of designers and engineers across multiple product teams building AI-native features.

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.
