Experienced data scientist with a strong background in fraud detection, recommendation systems, visual search, and natural language processing (NLP). Skilled in both classical machine learning and deep learning techniques. Led projects to stop fraud and account takeovers, and built smart systems that recommend products and understand images or text. Good at working with cross-functional teams, bringing in third-party models, and making sure models are accurate, fair, and well-governed. Also experienced in using large language models (LLMs) to find trends and help businesses make better decisions.
