About this role
Within ArcelorMittal's CMO department, the Data Science team is responsible for developing models that help commercial teams optimize the prices offered to clients, and for building intelligent dashboards to support business decision-making.
In this context, I was responsible for the dashboard dedicated to forecasting future prices based on market indices. This dashboard integrates three-month forecasts, providing strategic support to the commercial teams on a daily basis.
I also developed a forecasting package that enables easy comparison and testing of different models, parameter optimization, and the integration of exogenous variables from various sources. This package is currently in production and its results are used daily by end users.
In addition, I contributed to the maintenance and development of the dynamic pricing tool used by commercial teams. A recurring part of the role involved translating business needs into concrete technical solutions through regular workshops with stakeholders.
