Created arbitrage strategies to become a main player on Ethereum by daily trading volume.• Architected and wrote market-leading optimised smart contracts in Solidity assembly language. Using miner-extracted value (MEV) we were executing daily trading volumes of £100 thousand. Gained exposure expanding to other EVM-chains like Polygon, Avalanche and Fantom.• Built the DeFi DEX models for protocols like Uniswap V2/V3 and Balancer. These models allowed us to simulate the effect of… Show more Created arbitrage strategies to become a main player on Ethereum by daily trading volume.• Architected and wrote market-leading optimised smart contracts in Solidity assembly language.
