Hello, this is David. My technical career began in the U.S. Air Force. After leaving the Air Force, I began a professional career in Information Technology. I went on to become certified by Microsoft as a Systems Engineer, Administrator, and Trainer. By CompTIA I was certified in A+ and Network+.

I have extensive field experience with multiple Fortune 500 companies administrating computer servers, desktops, laptops, tablets and IP phones.

在公共和私人机构,我指示courses and tutored students in Microsoft certifications, CompTIA certifications, basic computer skills as well as math and reading.
