• Received a bug bounty for disclosing an issue in a popular NFT DeFi smart contract, preventing ~$55k of Ethereum from being stolen by bad actors - Discovered a complex reentrancy exploit to circumvent all address uniqueness checks and bypass timelock requirements of the DeFi smart contract - Produced proof of concept exploit written in Solidity using forge foundry - Worked with owners of the DeFi smart contract to prevent exploit and eliminate the attack surface• Built a custom Ethereum token (ERC20) arbitrage bot operating on across many DeFi (decentralized finance) smart contracts using Golang, Rust, and Solidity. - Employs advanced mathematics to discover market opportunities by forming arbitrage opportunities as a Convex hull optimization problem, drastically reducing computation requirements for said opportunities (compared to common shortest path graph-based solutions) - Uses extensive smart contract optimizations to deploy arbitrage transactions - Makes use of complex flash loan strategies to circumvent the capital required to execute arbitrages• Pioneered a method of fractionalized NFT arbitrage between various DeFi platforms

• Designed and developed iOS and Android app (Active4me) which motivates elementary school students to bike or walk to school. Currently used by over 200 parent volunteers who have logged over 200,000 green trips to school• Designed and developed iOS app (Active4me Run Club) that records students' laps around a track. Currently logging over 3000 student laps per day

• Developed a number of modules in Swift for production apps used by various pharmaceutical companies• Responsible for large portions of iOS app UI/UX design• Built continuous integration server using Jenkins (outputs build status to Slack)• Team lead for developing and implementing unit tests for iOS codebase

• Provided Ruby on Rails development and technical assistance to incubated companies• Had the opportunity to participate in AngelHack 2013 to help develop MVP for incubated company
