Contributed to FoleyLab/data_repository by developing and maintaining spectroscopic data resources for CO and CO2, focusing on data management and repository hygiene. Added new CSV datasets containing fundamental frequency measurements, enabling data-driven spectral analysis and calibration workflows for both CO and CO2 isotopes. Ensured accurate metadata alignment and stable access paths by correcting file naming inconsistencies, which improved discoverability and reduced user confusion. Maintained clear, traceable commit histories to support reproducibility and auditability across projects. Leveraged skills in data management and CSV handling to deliver reliable, well-organized datasets, supporting downstream modeling and validation efforts within the scientific data repository.
