PROFILE

Saar Shen

Worked on microsoft/perfview and microsoft/mcp repositories, delivering two features over two months. Developed OpenTelemetry SDK Activity event processing integration for PerfView, enhancing StartStopActivityComputer to support EventSource-based ActivityStarted and ActivityStopped events. This improved tracing fidelity and diagnostics for OpenTelemetry SDK activities, leveraging C# and Event Tracing for Windows to strengthen observability and troubleshooting. In the microsoft/mcp repository, implemented a new Azure CLI command to surface Application Insights optimization recommendations at scale, including command-line scaffolding, service integration, and unit testing. Focused on robust software design and integration testing, the work enabled actionable insights for cost and performance improvements in Azure environments.
