Linux System Administrator | Reliable Server & Cloud Solutions | Server Administrator

I am a highly skilled Server Administrator with extensive experience managing and maintaining both Linux and Windows servers in physical and virtualized environments. Over the years, I have built strong expertise in system installation, configuration, optimization, patching, and troubleshooting, ensuring maximum performance, stability, and security for business-critical infrastructures.

My technical proficiency covers a wide range of areas, including:

Linux Systems (CentOS, Ubuntu, Debian, RedHat, AlmaLinux, RockyLinux, etc.)

Windows Server Environments (AD, DNS, DHCP, IIS, RDP, Group Policies, etc.)

Virtualization Platforms: Proxmox, SolusVM, VMware ESXi, Hyper-V, KVM, and OpenVZ

Server Security: Hardening, firewall configuration (iptables, firewalld, UFW), intrusion detection, SSL/TLS, and patch management

Networking: IP configuration, VLANs, routing, load balancing, and VPN setup (OpenVPN, WireGuard, IPSec)

Server Optimization: Performance tuning, resource allocation, and monitoring using tools like Nagios, Zabbix, Grafana, and Prometheus

Backup & Recovery: Implementation of backup strategies (rsync, Bacula, Veeam, etc.) and disaster recovery planning

Web & Database Servers: Apache, Nginx, MySQL/MariaDB, PostgreSQL, and PHP stack management

In addition to core server administration, I have strong experience with virtualization and containerization solutions, including the design, deployment, and management of multi-tenant hosting environments, VPS provisioning, and containerized workloads (Docker, LXC). I am comfortable handling cluster management and high-availability setups for enterprise-grade infrastructures.

I take pride in my ability to analyze and resolve complex system issues quickly, minimizing downtime and ensuring uninterrupted operations. My approach is always structured and security-focused, combining best practices in system administration with client-specific requirements to deliver reliable, scalable, and future-proof solutions.

Whether it’s migrating legacy servers to modern platforms, deploying and securing new infrastructures, or troubleshooting mission-critical production issues, I bring a proven track record of delivering results under pressure.

If you are looking for a dedicated, detail-oriented, and technically strong server administrator to manage your Linux/Windows servers or virtualization platforms, I am confident I can contribute to the stability and growth of your IT environment.
