About Me
I enjoy taking products from zero to one. Over the past few years, I've built full-stack web and onchain applications using Next.js, React, and Solidity. I led development on Milady Colombia, Chonkpool, and Hypachinko, and worked on AI Arena's onchain infrastructure at ArenaX Labs. This past year, I also shipped full-stack features at SAI. I'm currently building out new ideas and open to new opportunities.
