    Since I completed my first IT course I have proven that I am a diverse individual with a wide range of capabilities and strengths who surpasses expectation more often than not. In one of my previous employment positions, for instance, I was initially hired as an IT support technician and ended up managing our company's entire operation in my region. Apart from management I filled the role of systems administrator at our client companies and got hands on experience with Linux Gentoo and Windows Server 2008, as well as a wide range of third party software such as Lexpro, Ghost Convey, Storedoc, and a variety of dictation software. My previous employment contract was with Platinum Health, the medical aid scheme for Anglo American.
