GIS Analyst | Geospatial Engineer | Climate & Risk Intelligence

Simon Mutunga
Mavindu

Building practical spatial data systems, climate risk models, and geospatial platforms — from geodatabase QA at national infrastructure scale to parametric insurance triggers and API-first agricultural intelligence.


3+ years in GIS, spatial data analysis, climate risk modelling, and remote sensing

100,000+ spatial records reviewed and validated in ArcGIS Pro geodatabases

Built risk intelligence systems covering deterministic logic, probabilistic logic, NLP, and geocoding

Experience across ArcGIS Pro, QGIS, Python, SQL, FastAPI, GeoPandas, H3, and remote sensing workflows
