Summary
🤩
Rockstar🎓
Top SchoolIvan Kalinin is a Senior System Administrator with 16 years of hands-on experience managing Windows Server environments, virtualization platforms (VMware, Hyper‑V, Proxmox), and Azure-based infrastructure. He has deep operational expertise across Exchange, SCCM, MS SQL, Cisco/MikroTik networking, telephony systems (Avaya, Asterisk) and enterprise backup and security tooling. Comfortable automating routine tasks with PowerShell, Bash and batch scripting—and recently leveraging ChatGPT—he combines practical automation with cautious change management (“I don't touch a system which I don't maintain”). Ivan pairs field-facing helpdesk and on-site support experience with procurement, vendor relations and staff training, making him effective at bridging IT operations and user needs. He also brings unusual cross-discipline skills for an sysadmin—experience with cryptographic tools and client-banking integrations, plus hobbies in digital art and Wikipedia translation that reflect an eye for detail and communication. Based in Moscow, he is known as a punctual, calm and highly trainable professional who continually seeks to expand his technical repertoire.
