Smart contract engineer and ecosystem team lead with nearly five years of experience at Gear Technologies, building across Ethereum and Vara. My work spans Solidity and Rust contracts, cross-chain bridges, token standards, and the architecture and launch of a DEX. I also review smart contracts, investigate vulnerabilities, and integrate cryptographic and zero-knowledge functionality.
I’m based in Madrid and looking for a remote Smart Contract Engineer role focused on Solidity/EVM, DeFi, or cross-chain infrastructure, where I can take ownership of contract development, security, and delivery.
