NicaraguaWhat I'm looking for
I'm currently supporting enterprise client environments at SMS Datacenter, managing Microsoft Azure, Windows and Linux servers, network infrastructure, Veeam backups, VMware virtualization, RMM platforms, and SecaaS antivirus solutions remotely.
At MT Solutions, I supported and administered client platforms using HPE and Dell PowerEdge servers, Fortinet security solutions, Microsoft Azure, VMware vCenter, and HPE Aruba networking. I delivered onsite implementation and support services.
I've led IT operations across Nicaragua, Costa Rica, and Panama, administering Microsoft 365 tenants, Windows Server environments, databases, data, voice, network, and backup services. I also managed teams of up to 10 IT professionals supporting more than 300 users and reduced inventory management time and costs by 20%.
My background spans telecommunications backbone networks, cloud infrastructure, virtualization, cybersecurity, and enterprise service delivery. I work effectively across global teams, time zones, languages, and cultures.
