Network Engineer and IT-Security manager - Team Lead IT Infrastructure and Operations

Reporting directly to the IT Director, I bring broad experience in network engineering, cybersecurity, virtualization, and firewall technologies. I have been training in and actively using Darktrace and Microsoft 365 Defender to detect, track, and investigate threats, while strengthening the organization’s overall security posture. I remain current on emerging threats, including ransomware, and apply that knowledge to help protect both on-premises and cloud-based systems.
My telecommunications background includes UCCX scripting certification and hands-on experience with call center technologies such as call queues, callback solutions, and account-based customer lookups. I am also knowledgeable in Azure Entra ID, Exchange Online, and general Microsoft 365 cloud administration, with experience supporting identity management, cloud messaging, and hybrid infrastructure.
In addition, I have hands-on experience with both AWS and Microsoft Azure, supporting hybrid cloud environments and contributing to the organization’s cloud administration and adoption efforts.
