Senior Solidity & De Fi Protocol Engineer
Senior Solidity and DeFi protocol engineer with 5 years of experience designing, building, and operating production blockchain systems. My work includes collateralized lending, vaults, staking and emissions systems, liquidity integrations, oracle-dependent logic, upgradeable contracts, and multi-chain deployments.
I work across the full protocol lifecycle, from architecture and Solidity development through Foundry testing, TypeScript integrations, deployment, monitoring, and post-launch operations. I am especially comfortable reasoning about liquidations, access control, reentrancy, upgradeability, oracle risk, economic edge cases, and how contracts behave under real market conditions.
I am looking for a senior Solidity or protocol engineering role where I can contribute to DeFi infrastructure, smart contract security, protocol design, integrations, and production reliability. I work well in remote, async teams and am most interested in lending, stablecoins, collateral systems, staking, vaults, and other technically demanding onchain products.
