Victor de Graaff began his career as a software engineer, but during his PhD research on Geosocial Recommender Systems, he discovered that learning from patterns is the most effective approach for generating quality recommendations. This insight led him into data science, where he developed impactful solutions for clients such as ING (fraud models), Heineken and Unilever (predictive models and promo optimizations), and Rijkswaterstaat (forecasting for asset management).
