Rüdiger Voigt
Business Intelligence Consultant and Software Developer based near Cologne, Germany. I work at GABO, part of Conclusion Intelligence, with a focus on Business Intelligence, Artificial Intelligence, and Data Engineering.
My work includes designing and developing reliable data warehouses and efficient ETL pipelines, as well as turning complex data into accessible insights through intuitive dashboards and analytical solutions. I also develop and deliver training sessions and executive workshops that help organizations use Business Intelligence tools, data, and analytics effectively.
With an academic background in Political Science, I bring an interdisciplinary perspective to my work. My interests include Artificial Intelligence, Data Science, and Comparative Politics, particularly where technology, data, and decision-making intersect.
