Choose a clear question
Start each project with a practical question such as what changed, which segment performs differently, or where a process loses efficiency. A focused question makes the analysis easier to assess.
Show the analytical process
Document the data source, assumptions, cleaning decisions, metric definitions, SQL or code, and validation checks. Employers need to see how you reason, not only the finished dashboard.
Explain the result
Add a concise summary of the most important finding, its limitation, and a reasonable next step. Avoid presenting a correlation or model output as certainty.
Keep the portfolio accessible
Use readable project pages, screenshots, repository documentation, and non-confidential data. Remove credentials, private employer information, and data you do not have permission to publish.
