PROFILE

Lunin Leonid

Over a two-month period, contributed to PTB-MR/mrpro by modernizing its documentation pipeline, enabling direct rendering of Jupyter notebooks in Sphinx using myst-nb. This eliminated manual HTML conversion, streamlined the CI workflow, and improved documentation accuracy and maintainability. Later, extended pytorch/ignite by adding 3D SSIM support for volumetric data, updating the metric and associated tests to handle 3D tensors. This enhancement broadened the library’s applicability to medical imaging and 3D vision workflows. Work demonstrated proficiency in Python, CI/CD, and PyTorch, with a focus on code quality, robust testing, and practical improvements to developer and user experience.
