📋 Description

• Design and build realistic toy/dummy datasets at varying complexity levels (simple, moderate, complex). • Ensure datasets reflect real-world scenarios while remaining clean, reproducible, and well-structured (CSV format). • Write concise, natural-language prompts (<40 words) tailored for business analysts. • Ensure prompts are grammatically precise and align with project style (non-technical, not overly directive, no raw metric requests). • Reproduce target visualizations with aesthetic and analytical fidelity. • Write clean, reproducible Python code using libraries like pandas, matplotlib, seaborn, and plotly. • Maintain high-quality code standards: well-commented, organized, and reproducible. • Define correctness criteria tailored to open-ended insight prompts. • Ensure criteria are flexible, accurate, and avoid assuming fixed solutions. • Provide supporting documentation with expected values and metrics (e.g., means, correlations, test results). • Rigorously check each example against quality rubrics (correctness, completeness, clarity, justification). • Maintain a high standard of accuracy across data, prompts, and visualizations.

🎯 Requirements

• 10+ years of professional experience in data engineering or applied data science. • Expert-level proficiency in Python (data wrangling, visualization, statistical testing). • Deep understanding of data modeling, prompt crafting, and reproducible workflows. • Exceptional attention to detail and quality control. • Proven success in high-impact technical environments.
