Hi, my name is Sadiq Qasemi. I am a Senior System Administrator and Data Center Expert with over 6 years of hands-on experience designing, deploying, and securing enterprise IT infrastructure.

Throughout my career, I have managed production data centers and disaster recovery environments. My core expertise lies in advanced Linux Administration, enterprise virtualization (Proxmox VE, VMware vSphere), and Software-Defined Storage, specifically building and managing large-scale Ceph Storage Clusters for high-availability environments.

In addition to my Bachelor's degree in Computer Science, I hold several major industry certifications, including Cisco CCNA/CCNP, VMware VCP, and Microsoft MCSA. I deal with real-world production technologies every day, including PCI DSS security compliance, containerization (Docker), and modern monitoring stacks like Prometheus, Grafana, and the ELK Stack.

As an instructor, my teaching philosophy is simple: I teach exactly what you need to know to survive and thrive in a real production data center. My courses bypass the unnecessary theory and focus heavily on practical labs, architectural design, and disaster recovery scenarios that IT professionals face in their daily jobs.

Whether you are a SysAdmin looking to upgrade your distributed storage skills or an engineer preparing for advanced data center operations, I am excited to share my real-world experience with you!
