Dmitrii Kazanin contributed to the Netcracker/qubership-logging-operator and qubership-jaeger repositories, focusing on observability, deployment stability, and configuration management for Kubernetes-based systems. He engineered features such as pod scheduling affinity, log level mapping, and Jaeger-Cassandra integration upgrades, using Go, Helm, and Lua scripting to address cross-environment compatibility and resource utilization. Dmitrii’s work included targeted bug fixes for TLS configuration, DaemonSet status reporting, and Graylog replica stability, as well as CI/CD pipeline hardening and container build automation. His approach emphasized reliability, maintainability, and production alignment, resulting in reduced operational overhead and improved troubleshooting for complex distributed deployments.

August 2025 across Netcracker/qubership-logging-operator and qubership-jaeger delivered stability, observability, and maintenance improvements. Key work includes Go/toolchain and container base upgrades to tighten security and consistency; hardened CI with reliable test execution and expanded logging; critical fixes to DaemonSet status reporting; and Jaeger chart/integration-test image updates to preserve compatibility. These changes reduce release risk, shorten feedback loops, and improve troubleshooting for production deployments.

July 2025: Focused on stabilizing telemetry for Netcracker/qubership-jaeger by disabling OpenTelemetry self-tracing in the Jaeger query component. Implemented deployment-level control (OTEL_TRACES_SAMPLER set to 'always_off') to prevent recursive/noisy traces, reducing overhead and improving telemetry reliability. Result: cleaner traces, fewer noise incidents, and faster root-cause analysis for query-related issues.
