As part of my role as a Flash Developer / UI Designer at PKR, I was heavily involved in upgrading the user interface. I developed a modular, component-based framework that enabled the flash team to build dynamic, consistent projects. I also focused a great deal on circumventing some of the limitations of AS2 (currently a requirement of working with ScaleForm). I injected many object-orientated AS3 techniques in order to keep the code up-to-date, concise, and also to ease the eventual transition when Scaleform supports AS3.
