What I'm looking for

I'm looking to apply geospatial data engineering, Web GIS, automation, and data governance to critical operational decisions, while leading teams and improving the quality, speed, and repeatability of spatial data delivery.

At Ikeja Electric, I govern spatial data for an electricity distribution grid spanning over 3,800 km and serving more than 1 million customers. I maintain enterprise PostgreSQL/PostGIS platforms for network, asset, customer, and operational analysis.

I've automated SCADA, billing, and field-capture integration with Python, ArcPy, GeoPandas, and FME, reducing manual processing by 67%. I also led deployment of a secure Web GIS platform covering 20,641 assets across 23 data layers.

I turn operational data into ArcGIS dashboards, Power BI reporting, and real-time KPI platforms that support faster decisions. My outage dashboards reduced mean incident-response time by 40%, while Survey123 digitization accelerated field data capture by 45%.

Earlier, I managed GIS teams and enterprise delivery at PoloSoft Technologies, administered mission-critical PostGIS environments at SpatialMatrix, and supported hydrocarbon exploration and large-scale mapping projects. I bring 15+ years of experience across GIS, spatial databases, ETL, cartography, and data governance.
