About me
Intro
I take a protocol from empty repo to audited mainnet: the architecture calls, the implementation, and the audit gate are all mine. Five years building production EVM systems, four in DeFi. At Portal to Bitcoin, a $110M+ funded protocol backed by Coinbase Ventures, I owned the smart contract layer end to end: a trustless BTC to EVM settlement engine, an on chain orderbook that replaced the legacy AMM, ERC-6909 multi token accounting, and validator staking with slashing. 15 contracts on mainnet, in production with no recorded exploit, audit reports public. I also conduct security audits. At Portal I ran a full security audit of the institutional OTC desk, covering the EVM contract surface and its TypeScript integration, delivered as a formal findings report. Open to senior protocol, smart contract, and Solidity engineering roles.

Owner of the smart contract layer at a $110M+ funded noncustodial cross chain protocol backed by Coinbase Ventures. Built from empty repo to mainnet. Designed and shipped the full EVM contract layer: 15 contracts on mainnet, 4 on Ethereum and 11 on Portal chain. Made the AMM to orderbook call and shipped the on chain orderbook that replaced it, cutting gas 70 to 80 percent across the system. Built the trustless HTLC settlement engine for noncustodial BTC to EVM operations. Owned the external audit as the release gate: reports are public. Built the deployment infrastructure and the governance machinery, with every mainnet deployment and privileged operation running through Gnosis Safe batch scripts I designed. Conducted a full security audit of the institutional OTC desk, covering the EVM contract surface and its TypeScript integration.
