Summary
🤩
Rockstar🎓
Top SchoolRobin Greif is a founder and quantitative software engineer based in Oxford with nine years of experience building high-performance ML and numerical systems for finance, fusion research, and AI-driven products. He combines a physics-first PhD background (Max Planck/Oxford) with hands-on engineering in Python, Rust, CUDA and distributed HPC to deliver practical, physics-preserving AI that has achieved orders-of-magnitude speedups in turbulence simulation. Currently consulting on structured product pricing, AI strategy/deployment and market analytics, he spans work from Raspberry Pi prototypes to InfiniBand HPC clusters and cloud deployments on AWS/GCP. An active open-source contributor, he has improved tooling like the popular word_cloud project and helped refactor differentiable PDE frameworks (PhiFlow), reflecting both pragmatic UX tweaks and deep backend restructuring. Known for preferring functional paradigms and pushing numerical performance (Numba/Cython/AVX), he also brings unusual breadth—ranging from fusion reactor design to digitizing historical texts with multimodal LLMs.

A little word cloud generator in Python
Role in this project:Software Engineer / Contributor
Software Engineer / ContributorContributions:19 commits, 1 PR, 1 comment in 4 days
Contributions summary:Robin primarily contributed to the enhancement of the word_cloud library by adding new features and improving existing ones. They implemented the `include_numbers` and `min_word_length` parameters to provide more flexible text processing options. Furthermore, the user wrote example files to demonstrate the usage of the new features, and included related tests. Additionally, the user made code formatting adjustments and corrected file endings.
