About Me

Derrick Demeveng - Spatial and Data Analyst, GIS Expert based in Ottawa, Canada

Your Personal Spatial and Data Analyst Consultant

I am a Spatial and Data Analyst with close to a decade of experience applying geospatial technologies and data science to address complex challenges in public health, population dynamics, and sustainable development, and construction industry. My work spans 5 continents, providing Geographic Information Systems (GIS), Data Analysis, and Business Intelligence (BI) supports to governments, institutions, and businesses for decision making.

My experience includes serving at UNFPA (United Nations Population Fund) where I support geospatial analysis for population data across 140+ countries, and at the World Health Organization (WHO) where I played a key role in polio eradication efforts across 47 African countries, developing innovative mapping solutions that contributed in early outbreak detection accross the Africa.

My team in WHO was recipient of the Esri 2024 SAG Award and I recieved the FIG Foundation Grant (2019).
