Message

At Afrobarometer, I ensure data quality across work in 40 African countries, build Power BI dashboards, and manage data pipelines using SurveyToGo scripts.

I conduct statistical analyses with Python and SPSS, and create visualizations with Power BI, Matplotlib, and Seaborn. I also lead the Data Quality team and train partners in data tools, statistical methods, and predictive modeling.

Previously, I designed survey tools and processed research data at BBC Media Action. At One To One for Resarch and Polling, I designed data collection programs for MENA region projects, supervised statisticians, and worked on data quality and analysis.
