Senior Protocol Engineer
I take a protocol from empty repo to audited mainnet: the architecture calls, the implementation, and the audit gate are all mine. At Portal to Bitcoin, a $110M+ funded protocol backed by Coinbase Ventures, I owned the smart contract layer end to end: trustless BTC to EVM settlement, an on chain orderbook, ERC-6909 multi token accounting, validator staking with slashing. 15 contracts on mainnet, in production with no recorded exploit, audit reports public. I also conduct security audits, including a full audit of an institutional OTC desk in production.

Senior Protocol Engineer. Owner of the smart contract layer at a $110M+ Coinbase backed DeFi protocol: architecture and implementation, empty repo to mainnet. Third party audit (Grey Swan, 2025), reports public. The critical finding closed the day the audit opened, and every remediation shipped before mainnet launch.
