What I bring to data and product teams

AI applied to critical workflows, on a solid engineering base

I combine generative AI, NLP and machine learning with the full data process behind data science: from structuring and data quality to modeling, automation and real-world applications. Experience in automated auditing, contract reading, clause extraction, compliance and technical information retrieval with LLMs and multi-agent systems.
