About
“I build React apps the way a designer would, with intent.”
I've spent 10+ years at the intersection of design and engineering, running a creative studio, leading teams, and shipping React products used by hundreds of thousands of people. I care about craft, speed, and interfaces that feel inevitable.

Craft Over Template
I build React apps the way a designer would, with intent. Every component is considered.
Performance Is a Feature
Speed isn't an afterthought. I optimize from architecture down to bundle size.

Managed a team of 7 engineers at Cinnamon. I know what shipping under pressure looks like.
