PROFILE
Nitin Kumar
Contributed to the JohnSnowLabs/visual-nlp-workshop repository by developing and maintaining end-to-end workflows for medical imaging data, with a focus on DICOM de-identification, OCR processing, and privacy compliance. Leveraged Python, Spark, and Jupyter Notebooks to build pipelines that automate de-identification of both pixel data and metadata, enabling privacy-preserving image-to-text workflows for clinical datasets. Enhanced the PDF-to-image and DICOM-to-image pipelines, improved notebook reliability, and expanded test resources to support robust development and reproducible experiments. The work emphasized code cleanup, data engineering, and machine learning techniques to streamline medical NLP tasks and ensure reliable, compliant data processing for research teams.
