Mubarek Mohammed

I am a Senior System Administrator with over seven years managing enterprise IT infrastructures across Windows and Linux environments, virtualization platforms, and network security. I focus on delivering reliable, scalable solutions that reduce downtime and lower costs.

I have led migrations to Microsoft 365, configured and optimized VMware ESXi clusters, and implemented Active Directory and Group Policy for large user bases, achieving measurable improvements such as 99.9% email uptime and a 30% reduction in downtime incidents.

I design disaster recovery plans, deploy centralized logging (ELK) for faster incident detection, mentor junior staff, and embrace automation and monitoring (Ansible, PowerShell, Nagios/Zabbix) to strengthen security and operational efficiency.
