I'm an experienced full-stack developer with a broad interest in web, mobile, and desktop applications. I have 8+ years of professional web development and Ruby programming experience. In my career I have shipped numerous client projects, from your run-of-the-mill Rails eCommerce sites to highly-custom modules for large-scale projects. I am interested and get involved in all stages of product development - from UI design through prototyping and development all the way to deployment. I value clear communication and clean code.
