Turn six messy CSVs into an analytics database and a Q4 dashboard that drives real business decisions. SQL + Claude.
The externship converted six raw CSV sources into a structured analytics database and produced a Q4 dashboard prototype. The work cataloged each dataset, mapped relationships across sales, products, and customers, and defined staging and fact tables for analytics. Deliverables included the database schema and a dashboard-ready data model.
I inventoried all six raw tables, produced five exploratory SQL queries with results (top products, catalog size, ad spend), and authored a running Week‑1 project brief summarizing dataset capabilities and gaps.
I inventoried each of the six raw data tables, noted what questions each could and could not answer, pasted five SQL queries with results (top products, catalog size, ad spend), and created a running Week‑1 project brief for the externship.
A fragmented set of four spreadsheets was unified by designing dim_product, assigning stable product IDs, and joining it with event and sales tables. I ran aggregation queries to produce a product performance table used to rank products by revenue and units sold.
During the externship I analyzed referrals, Meta campaign and sales data, calculated CTR, CPC and ROI per campaign, and produced a Q4 ad allocation plan that linked $37K in Meta spend to $61K sales and recommended campaign-level reallocations.
The project examined exported checkout records, identified bot-like sessions (high quantities, rapid duplicate accounts, odd shipping-to-subtotal ratios), created a filtered view of clean checkouts, and recalculated the abandonment rate excluding noise.
