I was tasked with coding the front end UI for Xbox One's out of box experience using XAML, including animations. Everything below is a screenshot, and a result of my XAML. Anyone who purchases an Xbox One will go through this experience when they first turn it on.

What is a Design Developer? I am a UX designer who has learned to code, UI Developer, knows the platform I am working in like the back of my hand, can rapid prototype, works with developers and designers and speaks both languages, works on helping design land their vision, polishes the UI in production code, expert in accessability, UI, UX, and reflowing visuals, and can bridge the gap between professions to help make sure the product is at its highest quality. We are the superheros between the product and its users to make sure the user experience is at its best.
