| Project | What it shows | Tools |
|---|---|---|
| Where do Hamburg's train delays come from? | 1.5M Deutsche Bahn stops. Long-distance delay is mostly imported: 84% on time for trains that start in Hamburg, 35% after 16+ earlier stops. | SQL (CTEs, window functions), pandas |
| E-commerce delivery and customer reviews | 96k orders. A late delivery costs about two stars (2.3 vs 4.3). | Power BI, DAX, star schema, pandas |
- Data-quality checks first, with every cleaning decision written down.
- Each result computed two ways (SQL and pandas, or DAX and pandas) and compared.
- Findings in plain sentences, with the limitations next to them.
