About me.

I’m a product designer, a strategic partner, and a hands-on builder with 8 years of experience, based in New York.

I turn complex ideas, emerging technology, and system constraints into clear and useful product experiences.

Currently, I design at Amazon Ads, building scalable tools and agentic systems behind a multi-billion-dollar business that processes trillions of daily advertising decisions.

Before Amazon, I was a Lead Experience Designer at Boston Consulting Group, building products and ventures 0 to 1 — taking them from concept to launch for Fortune 100 companies.

Outside of the office, I build digital products of my own, collaborate with artists on media art exhibitions, and make things with my hands.

I design with intention and execute with care. Let’s build what’s next.
