PROFILE

Lunin Leonid

Leonid Lunin contributed to PTB-MR/mrpro by modernizing its documentation pipeline, enabling direct rendering of Jupyter notebooks in Sphinx using myst-nb. He updated the CI workflow and configuration to streamline notebook integration, removing the need for manual HTML conversion and improving documentation accuracy and maintainability. In pytorch/ignite, Leonid extended the SSIM metric to support 3D tensors, enhancing volumetric data analysis for applications such as medical imaging. His work involved code refactoring, test updates, and integration of PyTorch-based image processing. Across both projects, Leonid demonstrated depth in Python, CI/CD, and documentation tooling, delivering targeted, maintainable engineering solutions.
