Portfolio

Eleven projects, each starting with a question

Every project has a working Excel model, a dashboard and a write-up explaining the method. Open any one on GitHub to download the workbook and change the assumptions yourself.

About the data: all portfolio projects use synthetic (made-up) data, so no client or customer information is shown. The questions, methods and recommendations are the ones we would apply to your real data.
