profile for Art Gillespie at Stack Overflow, Q&A for professional and enthusiast programmers


I'm a software engineer with insatiable curiosity and a deep passion for product development and user experience. I also have experience leading small, agile product teams to successful delivery of world-class products at Google, Nest, and Origami. If our work doesn't help somebody be more productive, safe, creative, or happy then what's the point?


I have deep expertise in engineering management, mobile and desktop media technologies, with dozens of shipped consumer apps over the past fifteen years. I'm expert with audio and image DSP including realtime applications, C++, C, and Objective-C. I'm proficient with Go, Python, Javascript and GLSL.
