ABOUT ME

I architect and build smart contracts that hold up when it matters. Over 500 deployed across Ethereum, Arbitrum, Polygon, and other EVM chains—DeFi protocols, token systems, staking mechanics, NFTs—each one written to survive real users and real adversaries.

Problem-solving is at the center of what I do. I break down complex protocol designs into clear invariants, trace edge cases before they hit mainnet, and optimize for gas and security in the same pass. I’ve learned that the best solutions come from asking “what can go wrong?” first, then designing around it.

Before Web3, I spent 13 years in enterprise IT—leading teams, owning mission-critical systems, and running multi-million dollar programs. That background shapes how I work: I care about reliability, clear ownership, and systems that don’t surprise you at 3am.

I’m drawn to hard problems: decentralization tradeoffs, trust boundaries, and protocols that stay secure as they scale. If you’re building something that needs to work under pressure, I’d like to help.
