Ian Ewell is an iOS GPU driver and compiler engineer with 11 years of experience designing and validating low-level graphics systems for mobile silicon. At Apple he has driven Metal shading language features and validated GPU blocks across A14 and M1 platforms, bridging compiler work and driver/user-mode integration. His background includes performance-focused graphics tooling at Google and NVIDIA, and large-scale distributed service experience from an Amazon internship, giving him rare cross-domain fluency in both hardware-aware software and production services. Known for squeezing power and performance—e.g., work that improved video playback efficiency at Chrome—he combines systems-level rigor with pragmatic implementation. Based in Cupertino, he excels at translating GPU architecture nuances into reliable compiler and driver features that ship on billions of devices.
