PROFESSIONAL SUMMARY

I have worked as a professional Computer Science Engineer for over 20 years. I have always had a love for ‘making things work’. My first college major was Electrical Engineering with electives in Mechanical and Structural Engineering. I have worked as a contractor/consultant in almost every industry imaginable from designing equipment to manufacture nuclear weapons to medical and gas well head controllers. The experience I bring to a job allows me to fit into a broad range of positions and to work well as a liaison between disciplines.

I studied Electrical Engineering at the University of Colorado until my third year. At that time, I transferred my credits to the University of Denver and completed my degree in Computer Science. This gives me an extremely broad base in software and firmware.
