Experienced in using FFmpeg/libav, Qt, 3D engines (Ogre 3D, Vision, Nebula, Godot, etc.), DirectX/OpenGL, Mono/GTK, GCC/MSVC, cross-platform development & porting as well as IT/development consulting.
Also constantly improving myself in topics related to game design and development, from engine topics to better algorithms for procedural generation.
