KenyaWhat I'm looking for
I’m a results-driven Senior Data Analyst with 8+ years of experience designing automated ETL pipelines, survey data quality frameworks, and analytics dashboards across 40+ countries. I specialize in Python, R, and SQL, with a strong record of cutting data processing turnaround times by 60%+ and delivering actionable insights for WFP, FAO, UNICEF, UNFPA, Plan International, and SFCG.
In my current role, I manage complex multi-country datasets end-to-end—from ingestion and validation through client-ready SPSS outputs and Power BI dashboards. I’ve built API-based real-time ingestion pipelines, automated quality checks (straight-lining, outliers, logical inconsistencies), and standardized validation frameworks that reduce post-delivery error correction requests by ~40%, while cutting QC review time by ~50%.
