Machine Learning / Data Science, DS LeadMy team of data scientists and analysts was developing machine learning models used in Sberbank's internal business processes. First of all, we analyzed the work of employees and built predictive models to assess the effectiveness of an employee's work and identify patterns of inefficient work.
