IT Systems Administrator with 7+ years spent keeping infrastructure running, secure, and scaling when it needs to. My background is in traditional systems administration, but my focus now is bridging the gap between on-prem servers and the AWS Cloud. Core Expertise: - Hybrid Cloud & Virtualization: AWS (EC2, EBS, VPC, S3), VMware vSphere, and Hyper-V. - OS & Patching: Managing Enterprise Linux (RHEL/SLES) and Windows Server. I handle updates and fleet maintenance through AWS SSM, WSUS, and YUM. - Identity & Access: Okta, Active Directory, IAM management. - Infrastructure Ops: DNS/FTP management, SAP R/3 (BRtools), and Workload Automation (TWS).
