Building an Open MEV Simulation Engine for DeFi Arbitrage

I'm Alessio Giannini, a Blockchain & MEV Engineer with a background in enterprise software development, now focused on DeFi, MEV, protocol economics, and execution security across EVM and Substrate-based chains. I build open source tooling for MEV analysis and cross-chain data collection under xchain-mev-research, and I work with protocols and operators on understanding and mitigating MEV exposure in production systems. Graduate of the Polkadot Blockchain Academy (Hong Kong, 2024). I write about what I build and what I find — MEV mechanics, DeFi infrastructure, cross-chain architecture, and the occasional deep dive into protocol internals
