<about/>

I'm a smart contract engineer passionate about building secure, scalable DeFi protocols. With a deep focus on protocol architecture and formal verification, I specialize in designing systems that maximize capital efficiency while minimizing risk.

My expertise spans ERC-4626 tokenomics, proxy patterns, and liquidation engines. I approach every contract as a security-first design challenge, leveraging tools like Foundry and Halmos to guarantee invariant correctness.

Currently Tech Lead @ Dione Protocol, architecting validator governance systems and securing 3M+ in protocol value. I'm drawn to problems at the intersection of economics, cryptography, and elegant code.
