aliahmad-1987/DataAnalystPortfolioProject_PBI_SQL_Python_MarketingAnalytics ? reverse-engineered prompt

Build me a marketing analytics portfolio project that shows the full workflow from raw data to a finished dashboard and presentation.

I want it to include SQL scripts to set up a small analytics model with customers, products, customer reviews, engagement data, and customer journey data, plus a Python step that cleans and enriches the reviews into a usable CSV. Then create a Power BI dashboard with useful marketing metrics and a calendar table so the visuals can be filtered by time. Please make it look like a real case study that I could show to employers, with a clear business story and a polished presentation slide deck at the end.

Keep the project practical and realistic, and use the files in the repo as the basis for the build. If anything needs to be checked against current best practices or docs, look it up online first.
