Levi DeHaan

Efficient Developer – I make every effort to develop code that is as efficient and robust as possible. I have been programming since I was a child, and have a deep love of computers and everything about them; I believe that development with a full understanding of your project will always lead to a better end product. I can lead projects or be led by a more experienced individual. I can plan and execute small or dramatic changes in a project. and due to my length of time in this industry, there is little I have not seen that I can't fix, build, install or create.
