    Remote Admin + Support Technician Specialist

    Australia - Last active: 3 months ago

    While I've spent the past 7 years adding to my arsenal of software and OS knowledge, bringing flexible problem solving skills to the table is the attribute that I'm most proud of. IT is usually perceived as a "hard-skilled", fact-based field, but my personal approach focuses on using my hard skills as a base and my soft skills as a conductor for reaching goals and building relationships. What I'm saying is, IT is really about the people. As you can see below, my technological skill base is high and varied - but I never forget about the positive attitude, strong communication and precise documentation skills that turn a project spec list into a well-oiled team effort. As my old manager eloquently referred to me as: "The go-to guy to get s**t done". Below is a list of my professional experience. -Operating Systems: Windows XP/7/8, Windows Server 2003/2008/2012 (including R2 editions) -Virtualization software: Vmware ESX, vSphere, XenServer -Software: Avaya CMS, CCE, Lync, Office 2003/07/10/13/365, MYOB, Oracle, SAP, VPN (Secureclient) -Windows Management Systems: Active Directory, ESM, GPO 2008, IIS, SCCM 2012, SCOM 2012, Sharepoint, Terminal Services -Backup solutions: Symantec backup exec, Windows NT backup, Drive Snapshot, -Anti-virus solution: Symantec Endpoint protection, Trend Micro Worry Free, Avast, BitDefender, Norton -Other Management Systems: Citrix, Teradici, Postini -Hardware: Servers, Desktops, Laptops, Printers -Networking: Modem + Router configuration + setup, Switch configuration, Windows DNS manager -Remote Support: Logmein, TeamViewer, VNC, RDP -Administration Skills: Vendor liaison/management, process creation/documentation/training, client management liasion -Mobile Devices: Android, BES, iPhone
