You do not need ten portfolio projects. You need projects that make your analytical ability easy to evaluate.
Start with one strong business question
Define the problem, decision and success measure.
Show the analytical process
Document data sources, cleaning, assumptions, SQL or Python work, metrics and validation.
Show the decision
End with what the analysis suggests someone should do and what additional evidence would improve confidence.
Reuse the project intelligently
One project can become a dashboard, SQL case study, portfolio article, interview story and short presentation.
AI can help you document and rehearse the project, but your reasoning should remain yours. Get the book on Amazon.
