  • 📍 Based in Leipzig, Germany

🔭 What I'm Working On

  • Building a portfolio with projects that solve real problems and are easy to understand
  • Strengthening my skills in Python, SQL, statistics and machine learning
  • Bringing a QA mindset into data work: clear structure, reproducibility and data quality

🧰 Core Tech Stack

🎧 Moosic Playlist Clustering

A capstone project exploring whether Spotify's audio features alone can group ~5,000 songs into playlists automatically. We tested DBSCAN for outlier detection and K-Means for clustering, narrowed 9 features down to 4 based on correlation and skewness analysis, and evaluated the resulting 46 playlists through silhouette scores and manual inspection.
