Security specialist focused on safeguarding complex blockchain systems across the Ethereum ecosystem. With 10+ years of engineering experience and deep expertise in L2, Rollup, and cross-chain architectures, I help teams identify critical vulnerabilities, secure on-chain assets, and ship with confidence. Experienced in both protocol engineering and security auditing, with a strong track record in analyzing high-risk systems, including DeFi, infrastructure, and privacy-preserving protocols. My core strength lies in bridging deep protocol understanding with adversarial security thinking—going beyond surface-level reviews to uncover non-obvious vulnerabilities in complex state transitions, cross-contract interactions, and economic mechanisms. I bring a full-stack blockchain perspective, with hands-on experience across protocol development, cross-chain bridges, zk-rollup systems, and dApps—allowing me to assess risks not just at the contract level, but across entire system architectures. I approach security from a system-level and real-world perspective, identifying where assumptions break and how small design flaws can evolve into critical failures in production environments. In addition, I have led engineering teams from initial design through production and commercialization, ensuring that security, scalability, and product delivery are aligned from day one.
