    I have been working in IT for over 14 years now, and loved almost every minute of it. While I have experience with everything from Netware to Windows to Aix on the administration side, I primarily specialize in virtualization now, particularly using VMWare (though I have used Hyper-V more than I care to remember). To help back up that systems experience, I also have extensive experience managing storage hardware, particularly EMC and Netapp SANs and Brocade and McData fiber channel switches. Combine this with my experience managing network hardware in one of the largest military campus networks in the Middle East, and everything in the virtual world is covered. I started my certifications with Novell and Microsoft, but have also received certifications from Comptia and Cisco at times, along with training from Netapp. Whether you are looking for someone to handle a small server issue or a full infrastructure upgrade and migration, my skills, experience and talents fit the bill.  less
