I'm a full-stack blockchain engineer with 2.5 years shipping production DeFi infrastructure — not prototypes, but live systems with real funds at stake. I've shipped upgradeable ERC4626 vaults with multi-protocol integrations, a cross-chain NFT collection that crossed $100K in trading volume, and a production ICO processing 134+ live transactions. I work well in early-stage environments where ownership is high and iteration speed matters.
