Back to original languageAbout Dr. Friedbert
Acquiring, processing, and analyzing large datasets is part of my daily work. The datasets to be analyzed were acquired from various sources and transferred to databases using ETL processes and further processed with Predictive Analytics. The focus in the software area is on Python and R. In the area of visualization, I mainly work with Tableau, Qlik, and Power BI.
