I specialize in the provisioning, securing, and continuous management of Linux server environments. From architecting traditional web hosting stacks to managing modern virtualized and containerized infrastructure, I deliver resilient, high-performance open-source solutions tailored for production workloads.
Systems Monitoring & Service Management: Adept at real-time performance monitoring and resource optimization using tools like htop. Proven track record of configuring and maintaining essential network and communication services, including Postfix, SpamAssassin, FTPd, and custom systemd service files.
Server Provisioning & Architecture: Extensive experience deploying and managing a wide array of distributions, including Ubuntu (LTS releases up to 22.04), CentOS and its modern successors like AlmaLinux, Debian, Kali, and CloudLinux. Proficient in managing bare-metal hardware, KVM hypervisors, Unraid storage servers, and Docker container workloads.
Web Stack Engineering: Expert in designing, deploying, and optimizing fully functional LAMP and LEMP stacks (Linux, Apache/Nginx, MySQL/MariaDB, PHP). Adept at utilizing enterprise management systems and control panels, including cPanel, Plesk, Webmin, Virtualmin, and DirectAdmin, to streamline hosting operations.
Security & Disaster Recovery: Focused on building hardened environments from the initial setup, including strict partition management, firewall configurations, and non-root sudo policies. Experienced in executing post-intrusion forensic analysis, comprehensive log management, and implementing robust disaster recovery pipelines using automated rsync, SFTP, and SSH backups.
Supported Environments: Ubuntu Server/Desktop (12.04 through 24.04 LTS), CentOS / AlmaLinux, Debian, CloudLinux, Kali Linux, Fedora, and Android.
Infrastructure & Virtualization: Provisioned and administered bare-metal servers, KVM hypervisors, Unraid storage pools, and Docker containers; executed OS installations, partitioning, and system updates. Mass monitoring of patches with PatchMon.
Web & Service Hosting: Architected production-ready LAMP/LEMP stacks (Apache, Nginx, MySQL, MariaDB, PHP); administered hosting environments via cPanel, Plesk, Virtualmin, Webmin, ServerPilot, and DirectAdmin.
Security & Access Control: Hardened infrastructure via firewall rules, SSH key authentication, and strict user access policies; managed mail and network services including Postfix and SpamAssassin.
Monitoring & Recovery: Profiled system performance utilizing htop; conducted post-intrusion log analysis and engineered automated disaster recovery and backup pipelines via rsync/SFTP.
