About
I am a results driven Public Health professional and Epidemiologist with over 10 years of experience across Africa leading Disease Surveillance, Outbreak Response, Immunization programs, and digital health systems rollouts. I have worked with WHO, ministries of health, BMGF, and USAID to train over 4,000 health workers, implement real-time data systems (ODK, DHIS2, GIS), and contributed to mass immunization campaigns reaching over 15 million children. I specialize in building systems that convert data into action, from training design to GIS-based risk mapping, from mobile data tools development to national dashboards. I’ve contributed to technical SOPs, coordinated international campaigns, and led digital innovation for VPD surveillance, including the Companion App pilot now adopted across WHO Africa Region. My mission is to bridge the gap between field data and evidence-based action. I’m open to global health consulting, epidemiology roles, M&E and digital surveillance projects both remote or field-based. 📩 Let’s connect to drive impact in global health.
