Dear Viewer, "Unlock the potential of your data with tailored, efficient, and impactful solutions." I specialize in helping businesses leverage data science and machine learning to solve complex challenges and drive strategic decisions. With expertise in Natural Language Processing (NLP), time series forecasting, regression analysis, classification, and anomaly detection, I develop and deploy models that deliver actionable insights. My experience spans multiple industries, including manufacturing, healthcare, and public infrastructure, where I’ve applied Python, transformer models, and advanced data visualization tools to create scalable solutions. Whether it’s performing sentiment analysis, optimizing manufacturing processes, or extracting insights from large datasets, I’m dedicated to providing high-quality, accurate results that align with your business needs. In addition to my hands-on experience, I hold a Master's degree in Data Science, which has further enhanced my ability to apply advanced machine learning techniques and NLP models. During my time as a graduate researcher in an NLP(Natural Language Processing) lab, I gained practical experience with BERT, RoBERTa, and ELECTRA models, as well as Knowledge Graphs and Named Entity Recognition (NER). My skill set extends to time series regression, feature engineering, and anomaly detection, which I’ve applied in multiple real-world projects. I am committed to delivering results efficiently, with a focus on clear communication and innovative problem-solving. Let’s work together to make data your greatest asset. Looking forward to collaborating with you! Thanks, Katie Minjoo Kim
