I have a set of well-formatted spreadsheets and database exports that I need explored for patterns and overall trends. The task centres on descriptive analysis only—no predictive modelling or causal diagnostics this time. I’ll supply the raw CSV files plus a short data dictionary; you return clean, documented code (Python, R or SQL—whichever you prefer), a concise write-up that explains the main findings, and a few clear charts that illustrate the key trends. Every step should be reproducible, so please keep scripts, queries and any notebook neatly organised and annotated.
