Worked on enhancing observability and performance analysis in the JetBrains/hirschgarten repository by implementing a feature that adds project-specific granularity to Bazel sync metrics. Focused on backend development using Kotlin, the approach involved augmenting the bsp.sync.project.ms span with a project name attribute, enabling per-project synchronization performance tracking. This improvement allows for more precise filtering and root-cause analysis in monitoring dashboards, supporting data-driven optimization and resource planning. The work demonstrated skills in metrics collection, distributed tracing, and observability design within a multi-repo environment, and included close collaboration with repository stakeholders to ensure alignment on instrumentation and traceability requirements.
