I’m sitting on roughly ten million rows of raw sales data and need a specialist to turn that mountain into clear, actionable insight. The core objective is straightforward: take the dataset as-is, clean it, explore it, and surface the key patterns that will guide my next decisions. You’ll work with whatever stack you’re fastest in—Python (pandas, NumPy, scikit-learn), R, SQL, or even a BI platform like Power BI or Tableau—so long as the final output is easy for me to digest and reuse. Cloud tools such as BigQuery or Snowflake are available if local processing won’t cut it. Deliverables • A cleaned, well-documented dataset ready for future queries • An analytical report highlighting the most significant sales trends and correlations • Interactive visuals or dashboards that let me slice the data on my own Accuracy, transparency on methods, and clear commentary are essential so I can validate and extend your work later. If this sounds like your kind of challenge, let’s get started.
