About me

Good work starts with curiosity.

I care about the details people notice and the invisible systems that make products work beautifully.

Over the last eight years, I’ve worked across design and engineering to help startups and growing teams launch products people actually enjoy using. My approach combines thoughtful interaction design, maintainable code, and a healthy obsession with performance.

When I’m not shipping products, I’m usually exploring new technology, mentoring developers, or walking through New York with a camera in hand.
