ColombiaWhat I'm looking for
I’m a Systems Support Analyst / System Administrator who manages and maintains IT infrastructure for healthcare and enterprise organizations with over 16 years of experience. I support critical operations by keeping systems reliable, improving performance, and strengthening security.
In my current role, I deploy and administer virtual environments using Proxmox across Linux and Windows and VMware environments. I also configure and manage network security (VPNs, firewalls, proxy services) and monitor systems performance using Zabbix to maintain availability.
