Synthetic Business CSV Analysis — Decision Report
Alden Cheng
Role: Data Analyst & Data Visualizer
Synthetic portfolio-process case showing how one structured CSV becomes exact KPI definitions, reconciled tables, readable charts and a concise decision memo.
The package preserves source grain, documents formulas and comparison periods, exposes caveats and includes a reproducible notebook plus QA manifest.
This is not client work and makes no causal or performance claim.
