Summary
🤩
Rockstar🎓
Top SchoolSemyon Danilov is a Senior Software Engineer with eight years focused on distributed databases, currently contributing to YDB at Nebius where he works on low-level storage, NVMe/SATA mechanics, shard storage and cluster management. An Apache Ignite committer and former core engineer at GridGain, he brings deep expertise in networking and persistence layers and intimate knowledge of the JVM while now writing primarily in C++. He combines hands-on systems performance tuning, some cryptography and tooling (clients, CLIs, Docker) with a history of teaching software engineering at the university level. Based in Ramat Gan, Israel, he is an active open-source maintainer with a pragmatic approach to storage internals and cluster coordination. Not obvious from his title: he routinely dives into byte-shifting and drive-specific behavior to squeeze real-world throughput and latency gains out of hardware. Reachable on GitHub as SammyVimes and on Telegram as @SemyonDanilov.
