Software Engineer II
Microsoft
Sep 2025 — Present
  • Designed and delivered a production classification system that processes application-usage telemetry from Kusto to identify high-risk Windows changes and improve compatibility decisions.
  • Defined a two-tier architecture that protects critical system paths while applying configurable usage thresholds to other changes, reducing unnecessary manual investigation.
  • Built service interfaces, Kusto integrations, caching, configuration controls, structured telemetry, fallback behavior, and selective downstream bug creation.
  • Demonstrated operational impact through controlled traces showing that the previous workflow generated 453 blocking candidates requiring manual review.
  • Built and deployed Safe OS regression detection, validation, and automated bug-filing capabilities for Windows servicing workflows.
  • Designed an authentication API and resolved production issues involving deployment, data access, background processing, file-system filtering, and runtime analysis.
  • Supported migration of a team-owned data platform to Azure SQL, including restoration, authentication, connectivity, application integration, and operational ownership.
  • Onboarded automated application-download and compatibility workflows to Hive Lab and GB300 pre-release systems.
  • Created end-to-end documentation covering deployment, scheduling, result processing, monitoring, infrastructure dependencies, and support procedures.
