Summary
🤩
Rockstar🎓
Top SchoolNipun Sadvilkar is a Director of NLP & Data Science based in Mumbai with a decade of experience building production-grade, multimodal AI systems for healthcare, currently leading a ~30-person team to deliver an AI-assisted medical coding platform. He spans the full ML lifecycle from large-scale data collection and annotation to deployment and monitoring, with deep expertise in NER, NLI, rules-based components, and low-resource language solutions. Nipun has driven NLP productization across Optum and Episource—translating clinical text into ICD-10 codes and scaling pipelines on Spark/AWS—and has hands-on engineering experience from backend services to frontend annotation tooling. An active open-source contributor, he improved sentence segmentation in the widely used scispaCy project and is the author of the pySBD sentence-boundary tool, showing his practical focus on robust text preprocessing. He blends technical leadership with teaching and community involvement (PyCon India, PyData, SciPy), and maintains a habit of writing about Python and AI, signaling a commitment to knowledge sharing beyond his enterprise work.
