01About

Two separate tracks.

I run two distinct careers in parallel — as an engineer I architect complex technical products at scale, and as a founder I build and lead companies across the beauty industry, pet care and supplements. They're independent pursuits; the mindsets just happen to sharpen each other.

The Engineer

11+ years building Web and Smart TV applications with JavaScript, TypeScript, React, React Native, Redux, Node.js, Next.js and Nest.js. I thrive on ambiguous technical challenges and squeezing out performance. As Chief Software Engineer of the JS department I led 26 engineers and set the architecture and standards the whole team builds on.

The Founder

CEO of Paws Power and LHL BIO, and co-founder of Beauty Power — independent businesses across the beauty industry, pet care and supplements, not tech products. I've taken a venture from zero to $2M in annual revenue in three years, owning strategy, operations, hiring and growth. Engineering discipline simply makes me a sharper operator.

02Ventures
