João Santos is a founder and smart contract engineer with 8 years in software engineering and 2+ years focused on DeFi protocol development. He has shipped production-ready Solidity contracts at Kaizen Labs, including Illuvium Staking V3 (TVL $2M+) and an NFT marketplace for Exeedme, and has led core contract architecture at Zaros Labs. Comfortable across frontend and blockchain stacks, he transitioned from senior frontend roles to architecting tokenomics, governance NFTs, vesting systems and gas-optimized reward distributions. An active security researcher with public audit reports on Code4rena and CodeHawks, he brings a security-first mindset to protocol design. Based in Brazil, he combines hands-on engineering with founder-level product ownership and a pattern of rapid, hackathon-proven delivery. A detail that often surprises collaborators: he pairs deep Solidity expertise with extensive production React/TypeScript experience, enabling end-to-end delivery from smart contracts to UX.
