At Hafmani Nigeria Limited, I performed spatial analysis in ArcGIS Pro to support infrastructure and utility planning. I also digitized satellite imagery and applied validation tools as part of a QA/QC process adopted team-wide, contributing to a 30% reduction in error rates.

I built and maintained four multi-user geodatabases and produced operational reports for land and infrastructure maintenance decisions. My work included energy auditing and analyzing electricity feeder data to support network optimization.

Earlier, I collected GPS-enabled survey data for a national health monitoring programme with the Country Coordinating Mechanism (CCM), and co-authored research outputs using spatial analysis and SPSS. I hold an MSc in Geographic Information Science from the University of Ibadan and am developing my Python skills for geospatial analysis and Earth Observation.
