Engineering leader building cross-chain DeFi.
Building cross-chain DeFi — from Solidity to strategy, from a single contract to a protocol with billions on the line.
VP of Engineering at Yei Finance, building Clovis — a cross-chain DeFi protocol enabling unified liquidity management across EVM chains through a Hub-Spoke architecture.
Previously CTO at Venus Protocol, the #1 lending protocol on BNB Chain, where we scaled to $2.8B supplied across eight chains with security as the first principle — 120+ audits in 30 months.
In blockchain since 2018 across every technical level — individual contributor, team lead, engineering manager and CTO. AI-assisted development is now woven through my daily workflow, from specs and smart contracts to testing and research.
