About Joseph Barker

As a system administrator with more than 18 years of experience in the industry, I am highly knowledgeable around many areas of IT. My most recent positions have allowed me to focus on managing projects, network administration, server administration, computer operations and tech refresh, procurement, along with managing help desk support,I am well versed in IT policy making and implementation including disaster recovery, business continuity, and cyber security training.I have strong skillsets in networking, windows server administration, security management, virtualization with Hyper-V and VMware, all while building relationships with vendors and users alike. I believe my skills make me an ideal candidate for a rapid and ever growing environment that requires quick response times with solutions to challenging problems.In my spare time I am a computer hobbyist that enjoys tinkering with advanced systems and different operating systems, web servers, and automation. Currently I have several automated processes that deal with DMV systems and Traffic Schools as well as working with a private school that allow for online classes to be taken.Please ask me for more information if you find this intriguing, I enjoy explaining how these systems work as they are side projects I have worked on for over a decade!
