Within a physicists and PhD students team, I developed extensions and hooks for virtual prototyping softwares, providing interactive controls and comprehensive interfaces during simulation processes. This results in cross platform code (Linux x86, Windows) written using C/C++ language, wxWidgets, OpenGL, plus several APIs. Part of the job included an advisor role about the use and evolution of the APIs with their respective provider. This scientific environment was a day­ to­ day challenge, where I was required to make mathematic abstraction more concrete.
