I design and build complex smart-contract systems and EVM protocol-level components, with a strong bias toward AI-assisted development. I combine production Solidity experience since 2017 with practical workflows that keep coding agents disciplined — separating generation from evaluation so the agent cannot grade its own work. My work includes protocol-layer development on an EVM L1 (Solidity contracts + Go/geth client), NFT-collateralized lending, DAO funding mechanics and account abstraction. Recent open-source work includes a 293-entry Solidity vulnerability knowledge base and a measured evaluation of AI audit workflows across a large real-world contract corpus. This approach is grounded in 20+ years of building complex backend, cloud and mobile systems. The same disciplined AI-assisted methods transfer well beyond blockchain, and I can work across or lead the integration of these layers when needed. Open to principal / lead engineering roles, fractional engagements and high-ownership project work.

Experience
Lead Smart-Contract & Protocol Developer
CORE Foundation (CoreDAO) 2023 - 2025
Protocol-layer work on Core Chain: Local Fee Market design (destination hotness / differential gas), CoreVault concepts, burn & emission policy, staking mechanisms. Built multi-node test environments and aligned genesis contracts with the Go client. Coordinated audits and hardfork preparation. Focus on gas-consumption behavior and fee-market mechanics at protocol level.
Lead Smart Contract Developer
DAOStack 2022 - 2023
Smart contracts for DAO funding mechanisms (pledgers, milestones, vaults, token flows, modify/exit logic).
CTO
NFTower 2021 - 2022
Full ownership of an NFT-collateralized lending platform. Designed and implemented core contracts (lending pool, loan lifecycle, collateral, interest, defaults, performance index, marketplace flows). Gas-optimized data structures (loan terms packed into 2 words) and clear on-chain / off-chain split.
CTO & Principal Software Architect
Mobile Edge Ltd 2009 - 2021
Led delivery of complex systems (including early production Solidity work in 2017). Large Android and server-side systems for Telefónica, Zoll Medical, SanDisk and defense customers.
