About this Gig

Is your Linux server down, slow, or not yet secure? I'll fix it and leave it clean, fast and documented.


I'm a Linux and virtualization engineer with 7+ years of hands-on experience running production servers, and I've taught Linux to thousands of engineers.


What I can do:

  • Fix failed services, boot problems, full disks, permission and network issues
  • - Set up and harden a new VPS: users, SSH keys, firewall, fail2ban
  • - Install and configure Nginx/Apache, databases and free HTTPS certificates
  • - Tune performance (CPU, memory, disk I/O) and clean up resource hogs
  • - Set up monitoring, log rotation and automated backups
  • - Write Bash scripts to automate routine tasks

Supported: Ubuntu, Debian, Rocky/Alma, CentOS, Fedora and most VPS providers (AWS, DigitalOcean, Linode, Vultr, Hetzner, etc.).


How it works:

  1. Message me with your problem or goal
  2. 2. Share SSH access (a temporary user is fine)
  3. 3. I do the work and send you a short report of every change

Please message me before ordering so I can confirm the scope.
