🌐 Eyouel Melaku — Senior Systems Administrator & Cybersecurity Engineer
Hi, I’m Eyouel, a Senior Systems Administrator and Cybersecurity Engineer focused on building secure, scalable, and automated IT environments. I work across Windows Server, Active Directory, VMware, PowerShell automation, cloud security, and detection engineering — designing hands-on labs and real-world solutions for systems and security teams.
I document my work publicly so others can learn, replicate, and improve their environments.
🚀 Core Focus Areas
Systems Administration: Windows Server, AD DS, DNS/DHCP, GPO, DFS
Automation: PowerShell scripting, patch automation, provisioning
Virtualization: VMware Workstation / vSphere concepts
Security Engineering: CIS hardening, PKI, identity security
Detection & IR: Sysmon, WEF, log analysis, threat detection
Cloud Security: Azure & AWS identity, IAM, hardening, monitoring
