I am transitioning from QA and Test Engineering into Data Science and Analytics. Currently I am studying Data Science & AI at WBS Coding School and building projects that combine analysis, structure, and practical usability.
- 📊 Focus: data analytics, predictive analytics and machine learning
- ⚙️ Background: 10+ years in QA, test automation and CI/CD workflows
- 📍 Based in Leipzig, Germany
- 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
Also working with: NumPy, matplotlib, seaborn, SQLAlchemy, APIs, JSON, Data Lake, Synapse
A Retrieval-Augmented Generation chatbot that grounds a local LLM in a Leipzig knowledge base, so every answer is built from retrieved sources instead of the model's memory. It includes a streaming FastAPI web UI, a CLI and a custom LLM-as-judge evaluation.

A Visual Studio Code extension for viewing and editing CSV and TSV files in a sortable, filterable grid directly inside the editor. It focuses on usability features such as inline editing, undo/redo, column resizing and theme integration.

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.

A full-stack library management app for tracking books, borrowers and loan history. This project helped me build hands-on experience with CRUD workflows, database structure and application logic.
