I keep corporate IT infrastructure secure, efficient, and running without interruption — and I don't stop at keeping it alive, I make it better. Networks, firewalls, virtualization, and cloud.
As an IT Specialist focused on infrastructure management and system operations, I make sure corporate IT processes run securely, efficiently, and without interruption. I work hands-on across network infrastructure, virtualization environments, Microsoft 365 administration, Active Directory, firewall configuration, and backup systems.
I actively deploy, manage, and optimize modern technologies such as M365, VLAN, next-gen firewalls, SD-WAN, NAC, SIEM, MFA, and cloud-based solutions. On the hardware side, I handle the full lifecycle of on-premise infrastructure — from HPE server installation and administration to Synology NAS deployment, configuration, and ongoing management. My approach isn't just to keep systems running — it's to continuously make them more efficient, secure, and sustainable.
