Leonard Püttmann is a Data Scientist at Kern AI, where the team builds a platform that accelerates LLM adoption for organizations working with text data. His work sits at the intersection of data science and natural language processing, helping teams move language models from experimentation into applications that create real value.

He is interested in all things machine learning, especially natural language processing, a field that has been transformed by large language models. At Kern AI he works on the practical challenges that come with that shift: curating training data, structuring text workflows, and making LLM-based systems dependable enough for production use.

Leonard is also a passionate tea drinker and always happy to talk about tech over a hot cup of tea, an approachable habit that fits the community-minded way he engages with the data science and NLP community.
