PROFILE
Olga Kuhn
Over eight months, Oliver Kuhn developed and enhanced data reduction pipelines for the pypeit/PypeIt repository, focusing on MODS and NIRES spectrograph support. He introduced new Python classes and refactored legacy code to streamline pre-processed data handling, improve configuration management, and broaden instrument compatibility. His work included robust bug fixes, data validation, and integration of atmospheric extinction curves, all aimed at increasing reliability and reducing manual intervention. Oliver also delivered comprehensive documentation and workflow guides, supporting onboarding and reproducibility. Leveraging Python, Astropy, and FITS file handling, he demonstrated depth in both engineering and technical writing across the project lifecycle.
