The workflow included a raw-data layer, cleaned dataset, validation log and summary to make the final database easier to review and use.

I organized the findings into an Excel research database, price benchmark and positioning analysis to make competitor information easier to compare and review.

Restaurant Profitability Analysis
I built an Excel-based restaurant profitability analysis covering revenue, food cost, labor cost, margins, menu performance, break-even analysis and scenario planning.
The project demonstrates how raw restaurant data can be structured into clear financial insights, practical recommendations and an easy-to-review dashboard.
