Ethereum Foundation core developer Sina Mahmoodi announces his departure, having been deeply involved in key infrastructure projects including Geth.

Ethereum Foundation core developer Sina Mahmoodi announced today that he is formally leaving the organization after over seven years with EF. He joined the Ethereum Foundation immediately after graduating from university in 2019, contributing to projects including EthereumJS (the TypeScript/JavaScript implementation of Ethereum’s execution layer), eWASM (Ethereum’s WebAssembly project), and most notably Geth (Go-Ethereum, one of Ethereum’s most core execution layer clients). Mahmoodi stated that he feels extremely fortunate to have worked alongside some of the smartest and most dedicated people on work he truly believes is meaningful, adding that he is particularly proud of his work on Geth, which has supported Ethereum through various challenging times and become critical infrastructure for its vast ecosystem. His belief in Ethereum remains unchanged: it is an open, global settlement layer that does not rely on any single government, company, or power center, and is worthy of continued development.
