Professional experience

Security Engineer - Detection & Incident Response

MICROSOFT · CLOUD OPERATIONS & INFRASTRUCTURE ENGINEERING · CYBER DEFENSE · 05/2026 - 09/2026

  • Engineered KQL detections across Microsoft Sentinel, Defender XDR, Palo Alto, and Defender for IoT telemetry.
  • Developed detections for suspicious parent-child processes, cross-zone lateral movement, and anomalous ICS/OT activity.
  • Validated detection fidelity using synthetic attack chains and positive, negative, and near-miss test cases.
  • Performed threat hunting across endpoint activity, Windows events, firewall traffic, and ICS/OT network telemetry.
  • Investigated high-severity, multi-site incidents using endpoint telemetry, firewall logs, routing data, packet captures, and Windows event logs.
  • Correlated security and network evidence to establish scope, evaluate root-cause hypotheses, and direct technical escalations.
  • Coordinated investigations across SOC, network, cloud, infrastructure, and site teams during complex operational incidents.
  • Converted incident findings into detection improvements, post-incident analysis, troubleshooting procedures, and response playbooks.

Network Security Engineer II

MICROSOFT · CLOUD OPERATIONS & INFRASTRUCTURE ENGINEERING · CYBER DEFENSE · 10/2022 - 05/2026

  • Designed and deployed zero-trust configurations across 150+ Palo Alto firewalls supporting global ICS/OT networks.
  • Managed Panorama onboarding, policy deployment, software upgrades, high availability, and security hardening.
  • Integrated Palo Alto firewalls with Azure vWAN and resolved BGP, IPsec, routing, certificate, and connectivity failures.
  • Deployed and supported Defender for IoT sensors and IDS monitoring across physical-security and critical-environment networks.
  • Analyzed firewall and IDS/IPS telemetry to validate policy behavior, investigate outages, and isolate upstream failures.
  • Assessed vulnerabilities and control gaps, translating findings into remediation plans and hardened configurations.
  • Coordinated global deployments and network changes with cloud, infrastructure, site, vendor, and security teams.
  • Authored technical designs, implementation plans, change procedures, troubleshooting guides, and operational runbooks.

Telecom Delivery Specialist - Lead
