DARIOCRUZ.DEV | Systems, Identity & Network Engineering
Welcome!
Hey, my name is Dario and this is my technical blog and engineering portfolio focused on Systems Administration, Hybrid Identity (Entra ID & Active Directory), Endpoint Engineering, and Enterprise Network Infrastructure.
What do I do?
With 7+ years of enterprise IT experience across financial services, national distribution, and large-scale fulfillment infrastructure, I specialize in keeping mission-critical systems reliable, managing hybrid directory and identity environments, engineering PowerShell diagnostic and automation tooling, and building resilient network topologies.
