About Me

I am a results-oriented Software Engineer and technology leader with 17+ years of international experience spanning blockchain, smart contract development, e-commerce systems and digital marketing — with a proven track record designing DeFi protocols, secure content systems and large-scale platforms.

My expertise lies in backend and blockchain engineering — from Solidity smart contracts and Layer 2 integrations to Node.js / NestJS micro-service architectures. I move fluidly between backend and frontend (Next.js, Vue, React) to deliver end-to-end products, from protocol design to user interface.

With strong leadership across cross-functional teams, I've served as CTO, Lead Blockchain Engineer and Senior Developer for organizations ranging from Nike (RTFKT) and Gameloft (Ubisoft) to LAMA Fintech, Privy Technologies and SMITHII — shipping DeFi protocols, fintech rails and content-ownership systems. Fluent in English and Spanish.
