Anna Hannemann is the Domain Owner for Data Science at Metro.digital, where she drives the story of data science and AI within the Metro business. In the domain owner role, she aligns data scientists across teams, turning scattered initiatives into a coherent portfolio of data products, from recommender systems to price markdown modeling that reduces waste.

Her career bridges engineering, research, and product leadership. Anna gained several years of experience in software development before completing a PhD in Data Science, then led product teams in recommender systems and robotics and smart logistics. Along the way she has worked through the practical questions that decide whether ML creates value: designing API-first recommender systems with approaches such as collaborative filtering and Word2Vec variants, sourcing problems from operations and validating them with MVPs, hiring data scientists, ML engineers, and MLOps specialists for production teams, and deciding who should own the decisions behind a model.

Beyond her day job, Anna contributes proactively to a range of initiatives focused on the enablement and empowerment of women in tech, helping more people find their path into data science and AI leadership.
