Top SchoolGuillermo Campanudo is a pragmatic full-stack engineer with six years of experience building web and blockchain applications from Portugal. He has shipped front- and back-end features using React, Next.js, NestJS and modern Ethereum tooling (ethers, viem, wagmi), and has hands-on experience writing and auditing Solidity smart contracts for DeFi protocols. At startups like AllianceBlock, ETHA Labs and Parifi he focused on integrating secure on-chain logic with user-facing DApps, and now applies those integration and process skills to telecom software and BPMN orchestration at ONI.
