WPF developer for the next generation rules, guidelines, and graphical UI application for the maritime shipbuilding industry. C# is the primary language along with Eyeshot Graphical 3rd party app. This was a non-standard implementation of WPF given that the predominant graphical interface was a 2D/3D UI (Eyeshot). What are termed Plain Old Common Objects (POCOS) formed the functional infrastructure to support the graphics UI. I did mostly C# coding fixing errors or completing implementations along with new and enhanced C# classes. Working on the graphical interface was integral to my work.
