About Me
System Administrator with 15+ years of experience. I specialize in
building fault-tolerant infrastructure from scratch and rescuing systems that perform poorly. My
expertise lies at the intersection of hardware (HCI, servers), databases (Oracle RAC, MS SQL Always
On),
and smart automation (Zabbix, Grafana, AI/LLMOps). I enjoy complex challenges that require
architectural transformation rather than simple maintenance.
