Summary
🤩
Rockstar🎓
Top SchoolRobert Kimball is a Senior Principal Engineer with 30+ years of systems and ML infrastructure experience, currently building production ML tooling at d-Matrix from his base in San Diego. He combines deep C++ backend expertise with practical Python-driven integration work, having led backend development for the open-source nGraph compiler and added TVM support to Triton and onnxruntime at OctoML. Known for solving "intractable problems" quickly, he repeatedly turns ideas into production-ready implementations—from high-performance dataloaders to GPU and NNP-T backends. His contributions to NervanaSystems/ngraph reflect a strong grasp of compiler and runtime architecture, memory and performance optimization, and operator design. Beyond shipping code, he brings a rare blend of low-level systems craft and product-focused pragmatism honed across Qualcomm, Intel, and startup environments.
