Summary
🤩
Rockstar🎓
Top SchoolJuan De La Rosa is a CTO and blockchain technologist with a decade of experience building secure Web3 infrastructure and smart contracts from Madrid. He has led product and engineering teams to deliver cross-chain bridges, token staking, NFT marketplaces, token vesting systems, and RAG-based AI integrations that blend DeFi and UX. As an independent consultant he honed hands-on Solidity, dApp, and security practices before scaling those skills into executive roles driving architecture and product strategy. Currently at Lid he’s architecting a creator-focused decentralized stack that enables self-owned commerce through NFTs, memberships and file sales. He pairs pragmatic engineering with an auditor’s mindset—frequently focusing on security and efficiency optimizations that aren’t obvious in product copy. Fluent across React/Next.js, Hardhat, Python and Node, he bridges frontend, backend and on-chain concerns to ship auditable, production-ready systems.
