Starting a Career in IT

Last updated Nov 13 2015

My path into working in IT was not a straight-forward one, coming from a mechanical engineering background. With some experience under my belt now in my professional IT career, there are some things that I wish I knew back in the day which I would now like to share with others. I’ll see if I’ll update this page periodically, but for now it is going to be rather bare-bones.

First of all, if you are still young, reading this right now, and do not have a post-graduate degree related to technology, I highly recommended that you get a computer science, software engineering or another related computing technology degree before venturing out on your own.

Otherwise, the following are some areas which IT professionals may choose to specialize in. I have mostly worked with software applications, and cannot comment on some of the other aspects of the IT industry, so the information may be incomplete in some areas.
