Software Engineer at Speedb
Israel
Summary
🤩
Rockstar🎓
Top SchoolAmnon Hanuhov is a software engineer from Israel with six years of experience building low-level, high-performance systems in C/C++, Java, and Python. A Technion graduate and alumnus of Israel's Magshimim cyber program, he focuses on operating systems, storage, and distributed systems and has worked on production-grade projects at Red Hat (Ceph/Crimson) and CERN. His open-source contributions to Ceph—adding benchmarking features, performance hooks, and robustness fixes—demonstrate a specialty in backend performance engineering for one of the most widely used distributed storage platforms. At Speedb he continues to apply that expertise to real-world products, and his academic project MedTabula became a top pick at the Technion fair and is live on the Play Store. Known as a fast learner and reliable team player, he pairs research-driven debugging with pragmatic engineering to deliver timely, quality software. An extra-strength detail: he has hands-on experience surfacing low-level metrics (CPU cycles per operation) and hardening OSD components against subtle corruption and EIO scenarios.

Ceph is a distributed object, block, and file storage platform
Role in this project:Back-end Developer
Back-end DeveloperContributions:52 reviews, 58 commits, 25 PRs in 2 years 1 month
Contributions summary:Amnon's contributions primarily focus on enhancing the Ceph distributed storage platform's backend functionality. Their work includes implementing Seastar metrics hooks for performance monitoring, removing obsolete flags, and addressing object corruption issues. They also made changes to improve error handling in Crimson OSD components, specifically regarding EIO errors and CRC mismatches, which led to object recovery mechanisms. Furthermore, the user refactored various messaging and connection components within the OSD, including the use of unique pointers for memory management and streamlined network operations.
