Summary
🤩
Rockstar🎓
Top SchoolJared Van Bortel is a software engineer with 10 years of experience specializing in Python, C++, and machine learning, currently working at Nomic AI in New York. He blends low-level performance work—like CUDA improvements and inference optimizations for llama.cpp—with practical ML tooling, including model conversion pipelines for gpt4all. Jared also contributes to core tensor library robustness in ggml, focusing on build stability, cross-compiler fixes, and code quality. Comfortable across cloud and infra tooling (AWS, Terraform) and production back-ends, he brings a pragmatic eye for performance and deployment. A detail-oriented contributor, he often tackles subtle issues such as null-pointer fixes and build reproducibility that pay off in large open-source ML projects.
