    • Identity & Threat Prevention: Spearheaded production migration from legacy key credentials to Azure Managed Identity worldwide; proactively intercepted customer PII leaks in telemetry, leaked secrets in incident logs, and data exfiltration architectural flaws prior to release.

    • High-Scale Performance Tuning: Overhauled core risk-alerting engines to achieve 30% lower alert latency with custom dynamic throttling; redesigned distributed trigger pipelines for 40% higher peak throughput with native fault tolerance, driving a 70% drop in customer-reported issues.

    • Distributed Data Engineering: Owned large-scale Apache Spark and Kusto data pipelines underpinning core trigger generation and user policy-scope datasets; root-caused complex distributed Spark failures by correlating monitoring telemetry across Kusto and Azure Data Factory (ADF).

    • Technical Leadership & Execution: Served as Tech Lead for network-based detection capabilities and strategic enterprise customer features; translated ambiguous product requirements into comprehensive HLD/LLDs, structured decision logs, and modular delivery kits.

    • AI-Assisted Engineering Innovations: Developed internal production-grade AI tooling including an Azure OpenAI LLM incident triage copilot (keyless auth, RBAC), MCP servers for automated dashboard investigation, and discrepancy detection agents; leveraged AI code reviews to intercept 20+ severe injection and crash bugs pre-commit.

    • Technical Mentorship & Multiplier Impact: Functioned as Senior Subject Matter Expert (SME) across three detection surfaces maintaining zero Sev2 incidents attributable to owned logic; mentored engineers into independent system owners, hosted 30+ architectural design reviews, and boosted team velocity by 20% through developer tooling.

  • Software Engineer, Microsoft Intune

    Jan, 2020 - Jun, 20222 years 5 months

    Owned core reporting infrastructure spanning 50+ microservices, enabling a 2x scale expansion in enterprise customer growth.

    • Microservices Redesign: Re-architected and deployed event-processing microservices for horizontal elasticity and scenario isolation, eliminating noisy-neighbor degradation and drastically reducing on-call alert fatigue.

    • Security Transformation: Discovered and remediated a long-standing secret exposure in core services with staged credential rotation; orchestrated ADAL to MSAL authentication migration and transitioned Kusto data access to secure token callbacks.

    • Platform Onboarding & Team Culture: Delivered account-move orchestration as the foundational PaaS service onboarding model; introduced pair programming practices, optimized on-call rotations, and mentored junior engineering talent.

  • Software Engineer, Microsoft Azure Maps

    May, 2018 - Jan, 20201 year 8 months

    Designed and scaled high-performance geospatial cloud services for Azure enterprise customers on a nascent product line.

    • API Modernization & Streaming: Redesigned batch and matrix REST APIs using advanced HTTP streaming to handle massive response payloads smoothly through GA release; simplified core routing infrastructure and built automated integration-test gating pipelines.

  • Software Engineer, Microsoft Azure Key Vault

    Oct, 2016 - May, 20181 year 7 months

    Engineered core security cloud services for cryptographic key, secret, and certificate management across global datacenters.

    • Managed Storage Account Keys (Preview to GA): Designed and shipped end-to-end REST APIs, secret management business logic, SDK extensions, national-cloud enablement, and soft-delete protection within a lean two-person team.

    • System Reliability & Resilience: Built automated customer-secret inventory tracking and redesigned multi-channel expiry notifications; contributed directly to company-wide mitigation and recovery efforts during major intermediate-certificate outages.

  • Software Engineer, Microsoft Bing

    May, 2016 - Oct, 20165 months

    Owned large-scale crawler and web-search indexing data pipelines.

    • Optimized high-volume bot-search data crawl, filter, and index pipelines while expanding customer service chat and messaging integrations across bing.com.
