A ProoV case study · educational project, not employment
Built an end-to-end profit investigation that combined structural problem framing, correct SQL analysis, root-cause ranking, and a recovery forecast. The work identified raw-material inflation, logistics inefficiency, and discounting as the main profit drags, then translated those findings into a board-ready recommendation set focused on margin repair and profitable growth.
