A ProoV case study · educational project, not employment
Built an end-to-end profitability investigation that framed hypotheses, audited the data, wrote the core SQL analyses, and traced the margin collapse to raw-material inflation, logistics inefficiency, and discounting pressure. Delivered an executive-ready recommendation set and board narrative that prioritized high-impact, low-effort actions to restore margins while preserving growth.
