I am a principal software developer at MathWorks. We make software for engineers and scientists. In the past, I have led a department of people reporting to me across a range of the application areas: math, signal processing, image processing, and communications. Together we planned the products we would ship and figured out how we would staff the projects. It was gratifying to see our work help others do their work. Currently I work with customers in key industries for MathWorks to help them understand how to make the best use of our products, especially the foundation one, MATLAB.
