Back to original languageAbout Rabii
With over 9 years of experience, I assist you in managing, securing, and optimizing your IT infrastructures.
Your IT infrastructure is the heart of your business. A breakdown, a security breach, a misconfigured infrastructure – and your entire organization grinds to a halt. This is exactly where I step in.
During my various experiences, I've learned to anticipate problems before they arise and to resolve them quickly when they do.
I have managed critical incidents on domain controllers, ensuring zero service interruption, because in this profession, downtime is not an option.
I master the entire IT chain: Windows Server administration, virtualization (VMware, Proxmox, Hyper-V), Active Directory & GPO security, PowerShell automation, monitoring, backup, and cybersecurity (pentesting, Fortigate/pfSense firewalls, SIEM, Zero Trust, MFA).
What you gain by working with me: a reliable, responsive contact who speaks technically but understands your business challenges. No unnecessary jargon, concrete and sustainable solutions.
Available remotely or on-site. Ready to start quickly.
