Month: 2025-03 — Tarantool/tarantool: CPU Metrics Monitoring upgrade focused on expanding visibility and reliability of CPU-related metrics. Key delivery includes introducing a new cpu_extended metrics category, accompanying tests, and fixing read-only status detection in replication metrics to avoid misleading indicators. This work improves observability, accelerates troubleshooting, and enhances capacity planning through more accurate dashboards.

November 2024: Strengthened migration governance and developer guidance in tarantool/doc. Delivered a Migration Troubleshooting Documentation Warning that clarifies manual intervention required for schema changes from incorrect migrations before they are fixed or cancelled, and that 'tt migrations' options only affect internal status and do not revert cluster changes. Impact: reduces operational risk, lowers support overhead, and aligns docs with actual migration behavior. Technologies/skills demonstrated: documentation best practices, change governance, and clear communication of complex workflows.
