Summary
👤
Senior🎓
Top SchoolAleksei Zakharov is a hands-on engineering leader with 11 years of experience building and operating large-scale Linux and storage infrastructure, now heading a team at Tinkoff focused on host-based firewalls. He began as a network and Linux systems engineer—setting up office and hospital networks—and progressed through datacenter operations, Ceph storage maintenance, and SRE leadership where he instituted SLAs and modern incident practices. Aleksei combines low-level expertise (kernel tracing, stack sampling, root-cause analysis) with practical observability work, contributing to open-source projects like collectd and prometheus/procfs to improve Ceph and bcache metrics. His background in managing critical on-call rotations and troubleshooting hardware, cooling, and power issues informs a disciplined approach to reliability and deploy-time safety. Colleagues note his shift-from-firefighting philosophy: prioritize root causes, schedule safer rollouts, and favor measurable SLAs over midnight patches.

Contributions summary:Aleksei primarily focused on enhancing the Ceph plugin within the collectd project. Their work involved adding support for a new Ceph version (Luminous) and improving how latency metrics are handled. The user refactored code to make the `node_handler_fetch_data()` function stateless and fixed issues related to parsing keys, contributing to the plugin's overall stability and compatibility. These changes are likely designed to improve the plugin's ability to collect Ceph metrics.
