If you are going to do Java programming, you'd have to get Java certified. If you want Microsoft (VB, VC++, C#, J#, etc) you'd have to get a MCSD. So it really depends on what languages you are going to use if you are going to be a developer.

I used to work with someone who was an Engineer, and not a programmer. I helped him learn the Visual BASIC language, and eventually he went and got certified and left the company to earn more money elsewhere. It didn't seem to matter that his degrees were in Engineering and not Computer Science or IT. At least not to the contracting company that hired him. As long as he could get the job done, that is all they cared about.

But be aware that the IT market is highly competitive, and you'd be going against people with 5 to 10 years or more of experience in the field. You'd most likely have to network to find a company that would hire you without the experience. Maybe get an Entry Level job and work your way from there?

Good luck, you'll need it.
