About William H. Smith

Information Security EngineerU.S. Navy veteranDoD Secret and Top-Secret security clearance eligibleEmployment Availability: Immediate - Dedicated professional with over 27 years working in Electronics and Information Technology.However, this was mostly hardware related, and I wanted to learn more about the software driving these devices or simply, the magic that makes it work.Completed 20+ weeks of software apprenticeship trainingCurrently a graduate student and pursuing a career in software development.In addition, I participate in the following:- CoderVets - Alpha company- several technical users groups- various hacking / programming events and challenges - and video game development eventsIn the Navy, I found that I was a natural at troubleshooting and fixing just about anything, from electronics to mechanical systems. After the Navy, I worked as a DoD contractor which I enjoyed but, I found that contract work was not as stable of a career as I would have liked. Also, due to my years in the navy, I found that I had developed a few physical limitations for some of the work required, like lifting heavy objects overhead for long periods of time. So, it was time to transition to a new career.I was very curious as a child and had a strong desire to learn and figure out how things worked.Often this involved taking apart nearly everything I could get my hands on to satisfy my curiosity. Needless to say, although understanding, my parents were not exactly happy with my adventures. However, it was ok because I could put things back together, well, most of the time that is. To this day, I maintain this same level of curiosity, minus the part about not being able to put things back together.Current: M.S. Management Information Systems graduate studentBachelor of Science (B.S.) focused on Management Information Systems, Business Administration, Cyber Security Certificate and a minor in Cyber Security.

Listed skills include Dod, Security, Emergency Management, Project Management, and 42 others.
