Summary

Rockstar🎓
Top SchoolGiulio Rebuffo is a project lead and backend-focused software engineer with nine years of hands-on experience building blockchain infrastructure, robotics integrations, and cross-platform applications from his base in Zug, Switzerland. He leads the Consensus Layer effort for Erigon—contributing substantial Engine API and block retrieval work to a well-known Ethereum client—while also coordinating external partnerships and team resources. Starting in robotics at 14, he still brings low-level systems skills (ROS, Arduino, C/inline assembly) alongside smart contract and Hyperledger projects, evidencing a rare full-stack fluency across embedded, distributed systems, and blockchain. His open-source portfolio includes contributions to Erigon and experiments like a Golang Ethereum wallet, ERC20/998 token innovations, and Hyperledger-based authentication and messaging prototypes. Notably, he earned B9LAB’s Ethereum developer certification as their youngest graduate, signaling both early aptitude and deep long-term commitment to blockchain engineering. Pragmatic and curious, he blends protocol-level thinking with practical tool-building and developer-friendly integrations.
