I'm a Senior Product Designer and Design Engineer with over 10 years of experience shaping consumer products end to end — from strategy and interaction design through to shipped, measured outcomes.

My path started in frontend development and technical product management, which is still how I work: close to engineering, fluent in the constraints, and comfortable moving from a flow diagram to a working prototype in React.

I've built and scaled design systems, run experimentation and design QA on products used by millions, and worked with distributed teams across the USA, Canada, LATAM and Europe. Lately, most of my focus is on AI-assisted design workflows and designing emerging AI product experiences.
