PROJECT BRIEF

What you’ll build

Turn a messy dataset into a small decision-ready dashboard. You will profile and clean the source, define reproducible transformations, verify important metrics, and present charts with clear labels, comparisons, limitations, and accessible tabular alternatives.

Core outcomes

Turn a written problem into a bounded, testable build plan
Make deliberate Python and PostgreSQL / Python implementation decisions
Produce concrete deliverables for every milestone—not only a final screen
Document the tradeoffs, validation steps, and release path for your portfolio

GUIDED BUILD PLAN

From first decision to portfolio proof.

Each stage produces a reviewable deliverable. Finish one before moving to the next.

01
Profile the dataset
Document columns, types, missing values, duplicates, outliers, and the decision the dashboard should support.
Deliverable: A data-quality report and question statement.
02
Build a repeatable pipeline
Clean and transform the raw input without manual spreadsheet steps, preserving source-to-output traceability.
Deliverable: A rerunnable Python transformation with tests.
03
Design decision-ready views
Choose a small set of metrics and charts, include filters, plain-language labels, and tabular equivalents.
Deliverable: An interactive dashboard with clear empty states.
04
Validate and publish
Cross-check totals, document assumptions, protect sensitive data, and deploy the dashboard reproducibly.
Deliverable: A deployed dashboard and metric-validation notes.

PROJECT FAQ
