Over the past few years I’ve worked in various capacities with several organizations and have gained a wealth of knowledge from each. As you can see, many of my past positions have been in warehousing and data entry; however all my employers have cross-utilized my networking and troubleshooting skills in addition to my normal duties. In fact my success in Information Technology is directly attributed to the troubleshooting skills I acquired while in those positions. I’ve utilized my problem solving skills with not only computers but people as well. More importantly, I use my troubleshooting skills to recognize and prevent problems before they happen.
