Technology Enthusiast

Introduction

I am an avid technologist with a lifetime love of computers and technology. As a result, I have experience with an extremely wide range of programming languages, operating systems, and technical positions. I bring a personable but professional attitude that enables me to motivate and lead teams of professionals in fast paced and highly technical environments. I have experienced two company acquisitions and regularly contribute to open source projects. In my recreational time I enjoy archery, sport driving, and of course PC gaming.
