GIS Data Analyst at Nuru Solutions processing satellite-derived agricultural data and building geospatial workflows for crop and drought analysis.

Kenya

Message

At Nuru Solutions, I develop geospatial workflows and web mapping services for agricultural data, processing vegetation indices to assess crop conditions and support yield-analysis workflows.

For the DigiFarm project, I conduct quality assurance on farm polygons, checking geometry and spatial consistency. I also integrate weather, soil, satellite, and administrative data for Agro-Ecological Zone analysis.

My work includes preparing SPEI-based drought assessments for Puntland, Somalia, and mapping irrigation areas and water bodies in Kaduna State, Nigeria. I use Python, GeoPandas, QGIS, ArcGIS Pro, and PostGIS to process and validate spatial data.
