Staff FDE / Product Engineer · Design Engineer · Frontend Engineer · AI-native builder
I'm a Product Engineer who works where design, product, and engineering overlap. Across 7+ years I've owned user-facing products end to end, from spotting the opportunity and designing the experience through building, shipping, and iterating on the live feature. My work spans React, Next.js, TypeScript, and full-stack delivery with Node.js, with the most recent focus on AI-native, agentic development.
Designer
I design the experience before I build it. Figma to production, one person.
Engineer
React, Next.js, TypeScript. 7+ years shipping user-facing frontends.
Product
I hunt for gaps in existing systems and go close them.
