About
I build production-ready blockchain systems that solve real security problems in cryptocurrency custody. Most recently, I co-invented and patented EthLock in collaboration with David DeMayo, CTO of Syntropy Software—a quantum-resistant Ethereum custody solution combining time-locks, multi-signature authorization, and orchestrated workflows.
Traditional cryptocurrency custody forces users to choose between security and usability. Custodial solutions require surrendering control. Self-custody demands technical expertise. EthLock solves this with workflow orchestration—users maintain complete control while the system guides them through complex custody operations step-by-step.
I develop full-stack blockchain applications from smart contracts to user interfaces. My technical expertise spans Solidity smart contract development, Python and Node.js backend architecture, React frontend development with MetaMask integration, and blockchain infrastructure including The Graph protocol and real-time indexing.
I approach development with a production-first mindset: no placeholder code, comprehensive error handling, cross-platform compatibility, and professional documentation. Whether architecting microservices for enterprise custody or building analytics dashboards for decentralized networks, I focus on systems that work in real-world conditions.
