I ship smart contracts, build the full backend, and audit the security — end to end.

5+ years across Ethereum, Polygon, and BNB Chain. Currently architecting a custom multichain indexing engine across 6+ EVM chains (replacing Alchemy/Moralis, sub-200ms). Previously led 5 engineers to ship 3 mainnet products: crypto billing (INTRXN), tokenomics (CURD), and DeFi debt-banking (FU Capital).

What I bring: Solidity smart contracts · ERC-4337 Account Abstraction · DeFi protocol integration · upgradeable proxies · smart contract auditing (Slither, MythX) · full-stack Node.js/TypeScript backends · AWS infrastructure
