As an R&D software engineer at Samsung Research America I fulfilled a native Android UI/UX developer role on an unreleased commercial Android project. I created the main screens and panels in addition to other parts of the UI framework, which included tasks such as complex 2D animations, communication with the back-end APIs, UX flow/transitions, UI performance benchmarking, and many core UI widgets (action bars, lists, etc.). I used Eclipse, Java and XML primarily on this project with Mercurial for distributed version control.
