• Lead Root Cause Analysis (RCA) for complex system outages or performance degradations. Utilize log aggregation tools and telemetry to identify issues across the application, database, or network layers.

• Maintain the Microsoft 365 GCC High tenant. Ensure all application configurations, integrations, and data flows adhere to NIST 800-171 and CMMC Level 2 controls.
• Maintain secure connectivity between on-premises Cisco/UniFi networking hardware and Azure Gov resources, ensuring application traffic is optimized and encrypted.
• Develop and execute rigorous testing and deployment plans for application upgrades, security patches, and database migrations in a zero-downtime-focused environment.
