Marijke Haupt

I am a Data Analyst with a focus on data preparation, data quality, exploratory analysis, and statistical methods. My experience includes data-driven projects in the financial and public sectors, where I have structured, cleaned, and analyzed complex datasets to identify patterns, anomalies, and optimization potential.

Data Analysis & Data Quality

At Commerzbank, I worked in the Big Data & Advanced Analytics cluster, analyzing the Master Data Management (MDM) inventory system, identifying error sources, and optimizing data structures. My focus was on data quality, process logic, and the analytical examination of large datasets to make technical and functional problems visible and solvable.

Process Analysis & Data-Driven Optimization

At VG Bild-Kunst, I was responsible for the structured processing of extensive datasets and the analysis of digital business processes. I cleaned data, checked relationships, identified discrepancies, and optimized processes.

Technical Skills

I primarily work with Python, R, Excel, and MatLab. My specializations include data cleaning, data preparation, exploratory data analysis, statistical methods, data mining, and the development of analytical questions. Through my ongoing Master's degree in Data Science, I am deepening my knowledge in machine learning, modeling, statistics, and data-driven methods.

Work Approach

I work in a structured, analytical, and detail-oriented manner. I understand complex data as the basis for well-founded decisions and as a starting point for process improvements. I communicate clearly, work independently, and navigate confidently between business departments and technology. Remote work is ideal for me; on-site appointments in the Cologne/NRW area are possible.
