Eric Gearhart’s Summary

I am experienced in the creation of secure information technology solutions that cover a range of platforms and architectures.

I am looking for an opportunity where I can utilize all of my talents and to be challenged on a daily basis. I enjoy facing a difficult problem or developing a solution that can increase the value received from a solution. I strongly believe Information Technology solutions should "get out of the way" and allow people to be more productive and make their lives easier.

In my experience I have learned that the best IT solutions are like puzzle pieces. They work best when they are tightly integrated together.
