A ProoV case study · educational project, not employment
Built an end-to-end profit investigation that framed hypotheses, audited the data, solved the core SQL analyses, and translated the findings into an executive storyline. The work correctly surfaced category and regional margin patterns, prioritized the main profit drivers with a Pareto lens, and packaged the case into board-level recommendations and a concise executive verdict.

What stood out6
- Wrote a correct category margin query using the required (revenue − cost) / revenue formula and grouped by category cleanly.

- Identified the likely profit drivers in a prioritized way, with raw-material inflation, logistics, and discounting ranked by impact.
- Communicated the paradox clearly in business terms, tying revenue growth, profit decline, and margin collapse into one storyline.
- Leakage-Free Analytical Framing
- Correct SQL Aggregation and Join Logic
