Practice Projects

Apply your skills with hands-on projects. Ordered by difficulty.

Synthetic Tabular Dataset Generator with SDV

Beginner

Build a complete synthetic data pipeline using SDV's CTGAN and TVAE synthesizers on a public dataset (e.g., UCI Adult Income). Profile real data distributions, generate synthetic equivalents, evaluate quality with SDV's QualityReport, and create a comparison dashboard. This project teaches foundational synthesis and evaluation skills used daily by synthetic data engineers.

Synthetic Data Quality Evaluation Dashboard

Beginner

Create an interactive Streamlit or Gradio dashboard that takes a real dataset and its synthetic counterpart as input, then displays distribution comparisons (histograms, box plots, correlation heatmaps), statistical test results (KS test, chi-squared), and ML utility scores from models trained on each. This project builds the evaluation mindset critical to every synthetic data engagement.

Privacy-Preserving Healthcare Data Pipeline

Intermediate

Build an end-to-end pipeline that generates synthetic electronic health records using CTGAN with differential privacy (Opacus integration), validates clinical plausibility with domain rules, runs membership inference privacy audits, and produces a compliance-ready quality and privacy report. Use the MIMIC-III or Synthea datasets as source. This project demonstrates the privacy-utility balance central to regulated industries.

LLM-Powered Synthetic Text Data Factory

Intermediate

Design a pipeline that uses OpenAI's API and LangChain to generate synthetic text datasets (e.g., customer support conversations, product reviews, clinical notes) with structured schemas. Implement few-shot prompting strategies, automated quality filtering with toxicity and coherence classifiers, and cost tracking. This project demonstrates the fastest-growing modality in synthetic data engineering.

Multi-Table Relational Data Synthesis Engine

Advanced

Build a synthetic data system for a realistic multi-table relational database (e.g., an e-commerce schema with customers, orders, products, reviews) that preserves foreign key relationships and conditional distributions across tables. Use SDV's Hierarchical Multi-Table synthesizer or build a custom sequential generation pipeline. Evaluate referential integrity, joint distributions, and downstream query fidelity. This is the most architecturally complex project, preparing you for enterprise-grade engagements.

End-to-End Synthetic Data Platform with CI/CD

Advanced

Build a production-grade synthetic data platform featuring a Python SDK for generation, Great Expectations quality gates in an Airflow DAG, DVC-based dataset versioning, MLflow experiment tracking, Docker containerization, and GitHub Actions CI/CD that automatically generates, validates, and publishes synthetic dataset releases. Deploy on AWS with cost monitoring. This capstone project demonstrates full-stack synthetic data engineering competency for senior roles.
