Professional Profile

I build Linux infrastructure that stays stable under real-world pressure

I am a Linux System Administrator focused on secure operations, practical hardening, and day-to-day reliability for production environments.

My process is direct: find risk early, tighten the baseline, automate the repetitive work, and keep visibility high so incidents are easier to diagnose and close.

I work in English and Russian and collaborate comfortably across infrastructure, security, and application teams.

How I Work

  • Reliability First: reduce operational surprises through hardening, standardization, and clear runbooks.
  • Security by Default: enforce least privilege, patch discipline, and auditable access patterns.
  • Automation with Intent: remove repetitive manual work without losing visibility or control.
