Most businesses are sitting on a database full of answers they have never asked for. I turn your raw data into specific, actionable business findings, using advanced SQL to answer the questions that actually matter.

You need to understand what your sales data is actually saying

You want to find which customers, products, or segments drive the most value

You need inventory risk analysis, revenue trends, or customer segmentation

You have a SQL problem that needs a clean, documented solution

A complete SQL analysis answering your specific business questions

Clean, commented queries using CTEs and Window Functions

A written findings summary in plain business language

Specific recommendations based on what the data shows

In my ClassicModels SQL project, I answered 7 business questions using SQL only — and discovered a 67:1 demand-to-stock ratio on a high-margin product that was completely invisible without proper analysis. I also identified a customer just $33 away from the next loyalty tier as an immediate upsell target.

In my Olist analysis across 113,000+ orders, SQL was the backbone of identifying which two sellers were responsible for 8% of all late deliveries across the entire platform.
