• Serve as the primary escalation point for engineering questions related to the system.
• Diagnose and resolve production incidents quickly, tracing failures end-to-end across Lambda, SQS, DynamoDB, SNS, and CloudWatch Logs.
• Support day-to-day VDI operations: image builds, bundle management, directory configuration, client connectivity, and user-facing troubleshooting.
• Bridge the gap between infrastructure automation and end-user desktop experience.
