Rahul Kumar

Python, SQL, PyTorch, TensorFlow, Hugging Face, Scikit-learn, LangChain; PySpark, OpenSearch, FAISS; AWS, Docker, Git, Linux. NLP/LLM/RAG specialist who goes broad when needed.

LLM fine-tuning & agents, RAG and retrieval at scale, model calibration and evaluation, and deeper MLOps (GPU training, serving). Always sharpening system design.

ML/NLP side projects — fine-tuning small LLMs, experimenting with RAG and agents, and automating model training & evaluation workflows. Plus the occasional open-source contribution.

Collaborations on ML/NLP and LLM projects, research discussions, paper/code chats, code reviews, and mentoring. Happy to talk RAG, fine-tuning, or careers in DS. Say hey! 👋
