Gerry Geurkink’s Resume

Owner/IT Consultant at HostGuardian.com
Lexington, Kentucky Area | Internet
Summary

I have extensive experience as an internet architect. Building large-scale database-driven sites with event-based traffic (large spikes) is what I do best. From the server build-out to published content, there is no layer I am not familiar with (including, but not limited to: initial requirements, concept, design, server installation/configuration, development, testing, migration, deployment, and SEO).

I also have over 19 years of network operations experience that includes the planning, implementation, and day-to-day operations of a variety of wired and wireless network environments – concentrating on security, redundancy, and overall network performance. Over 13 years of management experience in team oriented technology departments.

Building networks, servers, and web sites is my life. From gigabit local area networks to carrier-grade PTMP and PTP wireless networks. From Linux/BSD/Solaris/Windows to Virtualization. From brochure sites and blogs to database-driven applications and video publishing platforms.

Specialties: Network operations, system administration, web application development, SEO, SQL database administration, content distribution networks (CDNs), scripting, disaster/recovery, high availability, clustering, automation, monitoring, virtualization (XCP/Xen/VMware), SAN/NAS, linux/unix administration, Windows administration, VoIP, VPN, fixed wireless (PTMP/PTP), firewalls, Cisco routers/switches, Citrix, security, active directory, Exchange, managed services, and data center management.
