Skype Universal Windows App (UWP)

I worked on the adaptation of Microsoft's visual design language and Windows 10's patterns into a Skype that should work across different form factors from desktop to tablet and mobile. I crafted the visual design for most of the screens (out of other designers' interaction design specs) and a toolkit for other designers to easily follow the system. This toolkit specified from how spacing and sizing should be applied to the use of each color and how it should work when scaling from desktop to mobile.
