El De-dog-lo
Software Engineer
Summary
🤩
RockstarEl De-dog-lo is a software engineer with 11 years of hands-on experience specializing in Ethereum tooling, smart contracts, and backend systems. Based in Morocco, he has significant open-source impact across flagship projects like web3.py, py-evm, Yearn and Brownie, contributing features, refactors, tests and EVM hard-fork implementations. His work spans plumbing (account abstraction, HD wallets, testing backends) to protocol-level contracts (Yearn strategies, staking and fee distribution), showing both security-minded design and practical integration with DeFi primitives. Comfortable across Python and Solidity ecosystems, he’s also implemented developer ergonomics such as CLI, plugin setups and config handling for tooling projects. A telling detail: he blends deep protocol knowledge with developer-facing improvements—shipping both Istanbul EVM support and user-facing CLI/config features in major repos.
