Open to new protocol engineering roles (remote)
Two years designing and building in DeFi on EVM chains. Deep expertise in EIP-2535 Diamond proxy, ERC-4626 vaults, ERC-7579 modular accounts, and composable DeFi integration (DEXs, lending, yield, cross-chain). At Blok Capital, architected a modular multichain wealth management protocol: Diamond proxy vaults with a CREATE2 factory, DAO-governed Facet Registry, multiple yield strategies, onchain indices with automated rebalancing, and CCTP + CCIP for cross-chain USDC transfers. Currently building in public and studying zero-knowledge proofs.
Coffer: Self-custodial, modular smart-vault protocol on ERC-7579 + ERC-4337 v0.7. Every user gets their own programmable smart account that holds their funds and executes DeFi strategies (Aave V3, Uniswap V2/V3). Pluggable validator/executor/hook modules, deterministic CREATE2 deployment (up to 10 coffers per user), an ExecutorRegistry for clean DEX routing, and a funds-safe KillSwitch that blocks capital-deploying actions in emergencies while always leaving withdrawals open. → repo
Vault Router: ERC-4626 compliant yield vault on the Diamond proxy pattern (EIP-2535), routing deposits across Morpho Blue, Aave V3, and Pendle PT strategy facets on Arbitrum. Curator-governed allocation with per-strategy caps, idle reserve enforcement, and a Facet Registry for strategy allow-listing. → repo
Uniswap V4 Diamond Hook: Upgradeable V4 hook framework using EIP-2535. Hook address stays permanent while logic is upgradeable via diamondCut, eliminating pool migration on upgrades. Solved V4's permission-bit address constraint by mining the CREATE2 salt once at deploy. → repo
ZK proofs: Working through the RareSkills ZK course (zero-knowledge proofs from first principles). Posting weekly progress on Twitter.
