Smart Contract Development & Blockchain Research
Welcome to my official portfolio. I design, audit, and research secure Web3 protocols and smart contracts.
About
Specializing in the security of decentralized systems, with a deep emphasis on LayerZero and cross-chain bridge architecture. My work centers on solving distributed systems challenges, ensuring message composability, and designing secure vault frameworks. Whether auditing DeFi protocols, NFT ecosystems, or complex omnichain integrations, I prioritize the reliability and resilience of the infrastructure. I translate deep protocol analysis into actionable technical insights and secure code to harden the future of the decentralized web.
