During the day job I help developers with everything from guidance with our Proprietary SDKs in Systems and Graphics to looking at performance captures and giving low level optimization advice for both CPU and GPU in "standard" video games and for VR titles too.
C++, C, x86-64, Shader languages (plus shader ISA for GCN based GPUs), with Python and Machine learning as a hobby pursuit. Outside of that I also care about music and skateboarding, economics and psychology
