Welcome to my corner of the internet, containing my personal ramblings on product design, software development, real-time graphics, texture compression, and performance optimization.
Professionally, I am technical product owner for Arm Performance Studio, a suite of performance analysis tools for Arm CPUs and Mali GPUs. I am also maintainer for the Arm ASTC texture compressor, the defacto standard codec for Adaptive Scalable Texture Compression. In addition to my personal blogs here, more of my blogs can be found on community.arm.com
