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 exports into a structured analytics database and a Q4 dashboard. The work involved inventorying each data source, designing a relational schema, and writing SQL to transform and load the data. Deliverables included the cleaned database schema, ETL queries, and dashboard-ready tables.
I took the raw exports, mapped their contents, and prepared the dataset for schema design, ETL, and dashboarding. Below are the discrete steps I completed to move the data from messy CSVs to analytics-ready tables.
