We are seeking an Intern for Cash Collection Forecast project to work directly with Jan Kriz, Senior Manager of Business Intelligence and Data Science. The intern will assist in customizing our Cash Collection Forecast project, which is a vital component of our Cash Flow Forecast process. This project uses cutting-edge techniques such as Timeseries Forecast with Prophet algorithm and regression forecast with XGBoost and Catboost algorithms to predict the amount of money the company will receive before the end of the quarter. The intern will be involved in recreating the current solution, primarily developed in SQL and Python, using Power BI, as well as testing new functionalities in Databricks and ML Flow, a low-code/no-code environment for Machine Learning projects. While Jan will guide and support the intern, we expect the intern to show a degree of independence and a passion for learning new technologies and approaches.
