Experience & Education.

Built and optimized cloud data workflows, backend systems, an internal Azure analytics dashboard, and automated test coverage for cloud consumption, telemetry, and billing analytics.

• Modernized legacy Scala ETL logic by rewriting and simplifying 20+ Azure Synapse data pipelines in PySpark, processing billions of Azure usage and billing records for Fortune 500 customers and internal Microsoft teams.
• Reduced runtime of 3 production Apache Spark pipelines by 75%, from 24 hours to 5–6 hours, through stage-retry fixes, worker scaling, partition pruning, and join optimization, accelerating customer reporting.
• Built end-to-end ETL data pipelines with Cosmos DB, Cosmos SCOPE, and Kusto/KQL to ingest, validate, and surface 80+ Azure telemetry metrics in a stakeholder-facing dashboard for usage and cloud performance reporting.
• Maintained and expanded 150+ Playwright E2E tests in TypeScript, increasing dashboard test coverage and stabilizing flaky tests across 3 dashboard domains.

Developed reliability and system validation test suites for prior and next-generation Xbox consoles.

• Built and maintained 6 Xbox reliability test suites in C# and C++, each containing 20–60 automated tests covering hardware, firmware, OS, networking, and thermal validation, supporting release readiness for 9 console programs.
• Stabilized long-running Xbox reliability tests by resolving memory leaks, port exhaustion, cross-stack failures, and test infrastructure issues, unblocking technicians and engineers across 7 global hardware labs.
• Automated Xbox test log extraction to Excel, reducing manual data entry for lab technicians.
• Improved code quality and security across 4 production repositories by resolving 120+ CodeQL issues in C# and C++, addressing vulnerabilities and maintainability risks.
• Refactored 41 legacy C# projects and migrated pre-built NuGet packages to reduce main repo build time by 30 minutes.

Built analytics scripts, dashboard metric tiles, and internal tools to surface Cortana usage insights for Xbox engineering teams.

• Developed Cosmos SCOPE analytics scripts (SQL, C#) to aggregate Cortana speech usage data, helping engineering teams identify high-impact voice features for Cortana’s release on Xbox One.
• Built 10+ OnePulse metric tiles and an ASP.NET dashboard in C# and JavaScript to visualize Cortana usage trends, improving access to voice-feature and speech-interaction insights.
• Collected 40+ speech samples across multiple accents and reported findings, supporting Cortana release readiness.

Supported students preparing for internships by teaching C# and IT fundamentals.

• Led weekly lessons covering C#, IT fundamentals, and CompTIA A+ preparation.
• Created study guides and practice materials to help students strengthen technical foundations.
