Turn six messy CSVs into an analytics database and a Q4 dashboard that drives real business decisions. SQL + Claude.
The externship converted six messy CSV files into an analytics-ready database and produced components for a Q4 dashboard. The work examined each data source, mapped schemas, and designed a relational model for analytics queries. Deliverables included a cleaned dataset inventory and database schema ready for dashboarding.
I organized the raw data sources, documented their contents and limitations, and established the starting point for database design and dashboarding.
