Vsevolod Darmanchev

junior linux engineer

Hello! I’m Vsevolod Darmanchev, a motivated Junior Linux Engineer passionate about system administration, automation, and solving real-world problems. I started out in a completely different field, but my drive for continuous learning led me to dive deep into the Linux world, where I’ve been honing my skills and recreating commercial-level scenarios at home.

My Tech Stack:

  • Operating Systems: Debian/Ubuntu, CentOS/RHEL, AlmaLinux, Rocky Linux
  • Virtualization: LXC/LXD, Docker, KVM/QEMU
  • Monitoring: Nagios
  • Configuration Management: Ansible
  • Clustering & High Availability: Keepalived, Pacemaker
  • Backup: Rsync
  • Web Servers: Nginx, Apache
  • Content Management: WordPress
  • Proxy: HAProxy
  • Distributed & Shared Storage: NFS, Samba, iSCSI

I built this site, linuxsysadmino.com, to share my experiences, mistakes, and the tools I discover along the way. My goal is to help other aspiring sysadmins (and keep myself motivated!) by providing hands-on examples, resources, and insights into everyday Linux challenges.
