Linux Software Dev

I have been developing software for Linux for over twenty years, both professionally and personally, in a broad range of fields. My primary programming language is C, but I do a lot of work in Python and C#, and I use or have used many other languages in a variety of environments and operating systems. Game engine, tools and logic development is my main focus, but all aspects of programming interest me. I very much enjoy problem solving, and I am quite skilled at finding and fixing tenacious bugs. General areas of work include graphics programming, physics simulation, 2D and 3D math, high performance multi-threaded programming, debugging, compiler development, model import, export and processing tools. Languages: C, C#, Python, GLSL/HLSL, C++, Objective-C, Ruamoko (Objective-QuakeC (I wrote the compiler)), 80x86 assembly Tools: gcc, git, autoconf, automake, make, Blender, Unity, DJGPP, OpenGL, bash, sed Operating Systems: Linux, MS-DOS
