FULL STACK ENGINEER

BuildingattheIntersectionofBlockchain,AI&Cloud

I'm Enrique Ibarra. I build production systems across three domains: DeFi protocols and smart contracts, AI agent infrastructure, and full-stack web applications. From ERC-4626 vaults to autonomous agent marketplaces to cloud-backed lending platforms.
