I provision and support production Linux infrastructure, from bare metal to HA services.
Russian FederationWhat I'm looking for
At Magnit Tech, I support production Linux infrastructure responsible for 3,000+ servers across five distributions. I’ve provisioned around 100 Dell, IBM, and Oracle bare-metal servers from virtual media through production readiness.
I build server networking, LACP bonding, repositories, NTP, and SSSD/Active Directory access. I’ve also migrated live 2 TB LVM volumes with pvmove without downtime and handled SAN, multipath, filesystem resizing, and recovery work.
I’ve deployed HAProxy and Keepalived HA pairs in front of application servers, alongside Nginx reverse proxies and TLS configurations. During monthly second-line on-call rotations, I investigate Zabbix escalations, OOM events, logs, hardware alerts, and service failures with developers.
Outside work, I run my own home infrastructure and build self-hosted services with Docker Compose, Ansible, Nginx, Grafana, and Git-based deployment. I’m currently learning Kubernetes and SELinux while targeting remote Linux support and infrastructure engineering work.
