SQL-Powered Operations Dashboard
Build a real dashboard in Tableau or Power BI from raw SQL — track an operational metric end-to-end.
PostgreSQL or DuckDBTableau Public (free) or Power BI
About this project
Modern BAs need data fluency. This project teaches the whole pipeline: SQL query design (with joins + aggregates), Tableau / Power BI dashboard build, and the design discipline of making it actually useful. Pick a public dataset (NYC Taxi, Stripe Sigma sample, GitHub Archive) and build the dashboard you wish a real BA would have built for that operation.
Why build this in 2026?
BAs without SQL + BI tool fluency are increasingly unhireable above entry level.
