About
Systems Administrator · Amman, Jordan
I’m Fakhri Thaher, a Systems Administrator with over 9 years of experience across network infrastructure, cybersecurity and IT operations. I’ve supported enterprise environments, led IT teams, and founded my own IT solutions venture.
My work spans Linux and Windows server administration, enterprise and SD-WAN networks (FortiGate, BGP, F5, Aruba), security operations (SIEM, incident response, firewalls and VPNs), and automation with Bash and PowerShell. This site is where I write down the practical knowledge I rely on every day — in Arabic and English.
