At Action1, I supported a cloud-based endpoint management platform, helping IT administrators with agent deployment, policy configuration, patch management, and vulnerability remediation. I investigated Windows, networking, and authentication issues using endpoint logs and AWS CloudTrail events and CloudWatch metrics.

At SONA Networks, I supported enterprise Windows devices and Microsoft 365 environments, including account provisioning and access. Earlier, I provided desktop and IT support at GAMA-1 Technologies and Syneren Technologies, working on system deployments, maintenance, and user issues.
