Hands-On Enterprise Linux Systems Administration & Server Hardening
If your production server is hitting, memory limits, running slow, or needs security locking, I can help. I handle production Linux deployments, tuning, and infrastructure with 11+ years of IT ops experience.
I focus on practical engineering, tuning kernel parameters, automating tasks, and eliminating bottlenecks under heavy traffic.
Distros & Platforms:
RHEL, Rocky Linux, AlmaLinux, Ubuntu Server, Debian, Proxmox VE, VMware ESXi.
Core Technical Scope:
Performance & Kernel Tuning: Optimizing sysctl.conf, TCP stack tweaks, RAM/swap, disk I/O, & high CPU loads.
Security & OS Hardening: Disabling root passwords, SSH key auth, Firewalld/UFW, Fail2ban, & SELinux.
Virtualization & Clustering: Proxmox VE, KVM nodes, storage pools, & high-availability clusters.
Automation: Bash deployment scripts & Ansible playbooks for repeatable setups.
Diagnostics & Stack Fixes: systemd crashes, web servers (Nginx/Apache), storage expansion, & RAID/LVM.

FAQ
Which Linux distributions do you support?
RHEL, Rocky Linux, AlmaLinux, Ubuntu Server, Debian, Proxmox VE, and VMware ESXi.
Do I need to provide SSH access to my server?
Yes, root or sudo SSH access with IP/key authentication is required to diagnose and configure the server.
Will these optimizations cause any downtime for my live services?
Most changes (sysctl, firewall, SSH lock-down) are applied live without downtime. If a system reboot or service restart is needed, it will be scheduled at off-peak hours.
