❓Are your GIS workflows slowing down your business? Contact me! 👉 I build automated GIS systems —helping organizations reduce costs, improve decision-making, and launch location-based products faster. Invite me for an interview & I will make a demo solution for you for free. Over the past 9+ years, I've built geospatial solutions for organizations including IBM, public health initiatives, a leading investment bank, and a high-growth AI startup. On Upwork, I've helped clients automate GIS workflows, build interactive mapping applications, and develop reliable spatial data pipelines that continue delivering value long after the project is complete. I don't just build maps—I build software systems powered by location intelligence. ⭐ What I Can Help You Build 🗺️ GIS Automation & Spatial ETL - Automated GIS workflows - Python automation scripts - Spatial ETL pipelines - GeoPandas & Shapely processing - Data validation and transformation - Batch processing for large geospatial datasets 🌍 Interactive Maps & GIS Applications - Mapbox & Leaflet web applications - Interactive dashboards - KML, GeoJSON, Shapefile processing - OpenStreetMap solutions - Territory mapping - Custom GIS tools 📊 Spatial Analytics & Decision Support - Location intelligence - Site selection analysis - Spatial reporting - Time-series analysis - Predictive geospatial analytics - Data visualization 🤖 AI + GIS Solutions - AI-powered GIS workflows - Intelligent document processing - OCR and spatial extraction - Geospatial data automation - Machine learning applications - LLM-powered geospatial tools ☁️ Backend & Cloud - PostGIS & PostgreSQL - FastAPI - REST APIs - AWS & Google Cloud - Docker - Database integration 🚀 Selected Project Experience Franchise Territory Automation - Built an automated Python and GeoPandas workflow that generated KML territory maps, validated geometries, and streamlined territory management.
