I’m a senior backend and smart contract engineer with over 20 years of experience in software engineering, including 7+ years building production-grade blockchain systems and DeFi infrastructure.
I specialize in designing and implementing secure smart contract systems, integrating DeFi protocols, and building scalable backend services that support real-world decentralized applications. My work spans the full smart contract lifecycle—from architecture and Solidity development to fuzzing, invariant testing, audit processes, and deployment.
I also design and build scalable backend services and APIs, with experience in distributed system architecture, event-driven integrations, and production-grade service platforms supporting complex application environments.
I also build AI-powered automation workflows that streamline development processes and improve engineering reliability across the stack. I’ve led engineering efforts across Web2 and Web3 teams and deployed smart contract systems securing millions in TVL.
