Summary
🤩
Rockstar🎓
Top SchoolFedor Sakharov is a Senior Software Engineer based in Berlin with 16 years of experience in systems programming, security and blockchain, and a Master’s background from Moscow State University. Since 2018 he has focused on Rust-based blockchain and networking projects, contributing to high-profile open-source efforts like rust-analyzer, libp2p, Polkadot and zkSync where he improved core compiler front-end behaviors, DHT logic, peer reputation and JSON-RPC proof endpoints. He combines low-level systems expertise—memory management fixes, stream combinators and build-system work for mobile air-gapped wallets—with distributed-systems know-how in production blockchain nodes. Comfortable across backend and occasional full-stack build tasks, Fedor regularly tackles reorg detection, transaction-type support and robust error handling. Colleagues rely on him for steady, high-impact contributions to critical infrastructure rather than flashy surface features.
