Sansar client
Sansar PC game client UI built using a C++ implementation of XAML called Noesis Engine. Every interaction and rendering effect had to be added manually, there was nothing "out of the box."
I spent a little over one year working in a completely different environment from JavaScript. With the right amount of hand holding and freedom I was able to transfer all of my experience building web applications to the game client. I introduced a more a modular style of coding to the UI code base, and started working on extending functionality with view properties and shared variables.
