What makes it work

A breakdown of the choices that make this portfolio stand out.

1

A documented, repeatable end-to-end project structure

The explicit SQL → cleaning → Tableau dashboard sequence maps directly onto real analyst workflows rather than an unstructured mix of snippets.

2

Entry made without a traditional pedigree

Landing a data analyst role in 2017 without a mentor, then documenting exactly how, is unusually useful evidence for self-taught candidates.

3

Public queries paired with a live published dashboard

His public GitHub SQL repo and Tableau Public dashboards are both public and linked, letting a reviewer trace query to finished chart.

What Data Analysts can take from this

Specific, actionable tips to apply to your own portfolio — no generic advice.

  • Publish the SQL/cleaning step and the visualization step as two linked, visible artifacts.

  • If self-taught, document your actual timeline and the specific projects that got you hired.

  • Structure your portfolio as a numbered project series to show clear skill progression.

  • Reuse a well-known public dataset if you lack real company data — analysis quality matters more than originality for a beginner portfolio.
