What I work on

01
Protocol engineering
Mechanism design and smart contract implementation on EVM chains, with attention to invariants, economic edge cases, and upgrade paths.
02
Integrations & infrastructure
Connecting protocols to the systems around them — indexers, keepers, oracles, and the operational tooling that keeps them observable.
03
Review & advisory
Design review and second opinions on architecture, before the expensive decisions harden into deployed bytecode.
