About David Han

Hey, I’m David and I’m a NYC-based technology professional. I solve problems, build solutions, and make things better. What I don’t know, I figure out. I drive innovation, collaborate cross-functionally, restore order to chaotic systems, and optimize for business success and minimum downtime, ensuring environments run quietly and problem-free. My experience ranges from leading IT infrastructure transformations, creating bespoke network architectures, cloud platform configuration (AWS, Azure, Google Cloud), supporting cybersecurity initiatives, vendor management, software/hardware provisioning, linux/unix system administration, shell scripting, to yes…even the occasional unplug and plugin approach.Always open to new connections and interesting opportunities!Skills & Tools: Networking (LANs, WANs, routing), Cloud Computing (Citrix, VMware), Cybersecurity (Firewalls, End-point protection, MDM/EMM, SentinelOne, CrowdStrike, Okta, 1Password, Jamf, Fleetsmith, Kandji), Healthcare Compliance (HIPAA, DOH, CLEP), ITIL & ITSM principles, Linux/Unix, Automation (powershell), Remote Desktop (TeamViewer, ARD, Terradici, Connect-Wise), MacOS & Windows, Collaboration (GSuite, Front, Slack, Microsoft Office 365, Slack, Zoom, Teams)
