• Contribute to pre/post-campaign analysis with clear commentary and recommendations. Ensure statistical rigor is applied to business recommendations.
• Extract, transform, and clean the data required for modelling and analysis purposes.
• Support the team in enhancing the efficiency of data pre-processing, analysis, and reporting (e.g., increased automation).
