Johannes Burr is a Senior Data Scientist based in Heidelberg with 11 years’ experience applying machine learning and AI to real-world systems, from transformer-based models for software error prediction to large-scale ETA models for rail operations. He blends a strong academic background in data science and operations research with hands-on engineering—contributing to performance-critical open-source rendering projects (Intel’s Open Image Denoise, Embree, OSPRay) where he modernized CMake builds, packaging, and core engine features. Comfortable across research and production, he has applied deep learning to autonomous driving, LoRA-tuned models, and transformer pipelines, showing a pattern of moving prototypes into robust systems. Notably, his open-source work reflects a DevOps-minded focus on reproducible builds and cross-platform support, a less obvious but impactful thread in his profile.
