What I'm looking for

I seek a senior infrastructure role leading secure, scalable cloud and data-center migrations with collaborative teams, strong security culture, and opportunities to drive vendor strategy and operational efficiency.

I have over 21 years of experience in IT infrastructure and systems management, with a comprehensive background in systems administration, network management, and cloud solutions. I focus on delivering reliable, scalable, and secure IT solutions that align technology initiatives with organizational goals.

At Bishop Museum I oversee hardware, software, data centers, servers, networks, and cloud environments and manage the Helpdesk Team and vendor relationships. I implemented ManageEngine's Enterprise Mobility Management (EMS), redesigned the LAN and upgraded Fortinet firewalls, built a production data center at DRFortress and a DR center at MTP, completed a 200 TB data migration, and implemented Office 365 MFA and FortiClient EMS with Zero Trust Network Access (ZTNA).

Previously I served as Network Engineer (Assistant Vice President) at American Savings Bank and Network Analyst for the State of Hawaii Department of Taxation, where I led data center migrations to ACI environments, replaced F5 load balancers with Radware, migrated VxRail infrastructure, and executed campus-wide switch refresh and VPN projects. My hands-on experience spans Cisco Nexus and ACI, Fortinet technologies, Radware and F5 load balancers, VMware virtualization, Dell storage, and enterprise backup appliances.

I excel at leading cross-functional teams, optimizing resources, negotiating with vendors, and improving operational efficiency while meeting business objectives. I am seeking opportunities where I can lead infrastructure modernization, cloud and data-center migrations, and security-first initiatives in a collaborative, growth-oriented environment.
