An interesting challenge to work on was the spacing system for three different operating systems. When working for such a wide number of devices you can tell the difference between thinking about space as separation of visual elements, and space as a variable that gives order and set the dimension of components for specific screen sizes. As a UI Engineer I had to come up with a common language for iOS, Android and Windows in defining specific spaces for margins, paddings or absolute positioning, that way we will know the behavior of a component, mantaining its consistency, no matter the operative system or screen size.
