Summary
👤
Senior🎓
Top SchoolHarold Wadleigh is a software engineer and applied mathematician with 17 years of experience specializing in 3D reconstruction and perception systems. He fell into computer vision after reconstructing scene geometry from satellite imagery in 2010 and has since worked across defense, autonomous vehicles, and embedded systems roles, now at NVIDIA and XPENG. A long-time Julia user and contributor, he has made core contributions to the Julia language—adding SharedArray Windows support and debugging/workflow improvements—and also contributes low-level embedded drivers to projects like ChibiOS-Contrib. His background blends rigorous academic training (UCLA mathematics) with hands-on systems engineering, from memory-mapped platform code to microcontroller UART fixes. Colleagues rely on him to re-evaluate and sharpen tooling, and outside work he often resets perspective by escaping into the mountains.
