Riley Nguyen Data Science • Graduating 2026
Data Science Portfolio

Data you can explain. Models you can defend.

I’m a soon-to-graduate data science student focused on practical analytics and machine learning— with an emphasis on reproducibility, clear evaluation, and stakeholder-ready storytelling.

  • Measurement first: clear metrics, baselines, and error analysis.
  • Readable outputs: charts and narratives for non-technical audiences.
  • Reproducible work: notebooks, versioning, and documented assumptions.
  • Pragmatic ML: interpretability and deployment-minded pipelines.

Projects

Replace each card with real outcomes, links, and artifacts (notebooks, dashboards, demos).

Churn Prediction + Action Drivers

Built a classification pipeline and translated top features into retention experiments and messaging.

Pythonscikit-learnSHAP

Forecasting: Demand & Capacity Planning

Backtested time-series forecasts and communicated uncertainty with confidence intervals.

Time SeriesBacktestingError Analysis

NLP: Review Insights Dashboard

Extracted themes and sentiment to highlight product issues and wins; packaged results in a dashboard.

NLPEmbeddingsTopic Modeling

Experiment Design Playbook

Created a lightweight framework for hypotheses, guardrails, power considerations, and interpretation.

StatisticsA/B TestingCausal Thinking

Writing

Short posts that show how you think: methodology, evaluation, and communicating tradeoffs.

Case Note

How I evaluate models beyond “accuracy”

Picking metrics that reflect business cost, calibration, and the user experience of mistakes.

Explainer

What makes a dashboard actually useful

Definitions, ownership, refresh cadence, and the “so what” layer that drives action.

Toolkit

My reproducible project checklist

Data validation, versioning, clear assumptions, and artifact structure for clean handoffs.

Skills

Keep this aligned with the roles you want. Be specific and credible.
