Arbin Timilsina is a Principal Data Scientist and manager in Boston with a decade of experience turning research-grade machine learning into production AI and analytics products. He leads teams that build metadata-driven pipelines, migrate legacy SPSS workflows to automated Python systems, and deliver on-demand insight engines that have multiplied delivery flexibility. His background spans advanced NLP and LLM work (LangChain, LlamaIndex, Hugging Face, OpenAI), production retraining pipelines for BERT variants, and building AI features into web platforms. Earlier roles in particle physics and computer vision inform a rigorous experimental approach—he once achieved a 93.8 IOU for semantic segmentation in neutrino detector data. Equally comfortable with cloud-native infrastructure (AWS, ECR, MWAA, SageMaker) and low-level research code, he blends scientific rigor with pragmatic productization to accelerate decision-making from messy, multilingual text.
