I'm a Database Analyst & Data Protection Officer at Credit Data CRB in Blantyre, Malawi, where I automate data quality processes, build monitoring dashboards, and ensure compliance with the Malawi Data Protection Act.
My expertise spans mixed-methods research — from complex survey analysis of DHS data in STATA to qualitative coding in NVivo. I've supported 10+ Master's and 3 PhD research projects across health and social sciences, and delivered analytical outputs for the National Planning Commission.
I specialize in data governance, including Data Protection Impact Assessments (DPIAs), system audits, data quality manuals, and ETL automation — bridging the gap between rigorous research and operational data infrastructure.
