Senior🎓
Top SchoolGabriel Fior is a Senior Full Stack Engineer specializing in the intersection of Web3 and AI, with 10 years of experience building production systems for financial institutions and DeFi startups. Based in Berlin and originally from Brazil, he has shipped solutions across Python, JavaScript, Java, Powershell and Solidity, and has led teams building high-throughput data pipelines (Kafka) and on-chain integrations across Ethereum, Cosmos and Solana. At Gnosis he built LLM-driven agents and RAG pipelines for on-chain prediction markets, reaching 75% forecasting accuracy, and at Chaos Labs he continues to blend agent-driven AI with blockchain tooling. As a founder (Deep Balancer) he combined deep learning for risk-adjusted crypto strategies with EIP-4626 vault design and regulatory thinking, demonstrating both product and technical leadership. He pairs rigorous academic training from TUM and Oxford with hands-on research experience (CERN simulations, phase-contrast tomography), giving him an unusual fluency across scientific computing, ML, and decentralized finance. Colleagues describe him as a builder who moves smoothly between low-level protocol work and applied AI productization.
