Hi, I’m a Geospatial Full-Stack Developer with 5+ years of professional experience and 50+ projects delivered, helping businesses, engineering firms, researchers, and startups turn complex geospatial data into fast, intuitive, production-ready web applications and decision-support systems. Most GIS data is valuable but if it is trapped inside ArcGIS/QGIS projects, spreadsheets, shapefiles, or disconnected databases, it becomes difficult for the rest of the organization to use. That’s where I come in. I combine GIS engineering, full-stack development, spatial databases, remote sensing, and AI/ML to build solutions that make geospatial data searchable, interactive, automated, and actionable. 🚀 What I Can Build For You ✅ Custom Web GIS Platforms Interactive mapping applications, GIS portals, spatial dashboards, asset management systems, parcel platforms, infrastructure mapping, and internal GIS tools. ✅ Interactive Web Mapping Applications High-performance maps using Mapbox GL JS, MapLibre, Leaflet, OpenLayers, Google Maps, ArcGIS APIs, CesiumJS, and other modern mapping technologies. ✅ Location Intelligence Solutions Geolocation search, proximity analysis, site selection, territory analysis, routing, spatial queries, location-based business intelligence, and decision-support dashboards. ✅ Spatial Data & GIS Automation Automated data processing, geocoding, ETL pipelines, spatial transformations, GeoJSON/Shapefile/KML/GeoTIFF processing, API integrations, and GIS workflow automation. ✅ Spatial Databases & APIs Designing and optimizing PostgreSQL/PostGIS databases, spatial queries, REST APIs, GeoServer services, vector data pipelines, and scalable geospatial backends. ✅ GeoAI & Remote Sensing Satellite imagery analysis, land-cover classification, object detection, spatial machine learning, environmental monitoring, agricultural analytics, susceptibility mapping, and geospatial prediction models. 🗺️ GIS + Full-Stack Expertise GIS & Spatial Technologies ✅ ArcGIS Pro / ArcGIS Online ✅ QGIS ✅ GeoServer ✅ GDAL / OGR ✅ GeoPandas ✅ Rasterio ✅ Shapely ✅ Turf.js ✅Google Earth Engine ✅ OpenStreetMap Web GIS & Mapping ✅ React / Next.js ✅ JavaScript / TypeScript ✅ Mapbox GL JS ✅ MapLibre ✅ Leaflet ✅ OpenLayers ✅ CesiumJS ✅ Google Maps API ✅ArcGIS API for JavaScript ✅ WMS / WFS / WMTS ✅ Vector Tiles Backend & APIs ✅Python ✅ Django / GeoDjango ✅ FastAPI ✅Node.js / Express ✅ REST APIs ✅ API Integration ✅ Geospatial Web Services Spatial Databases ✅ PostgreSQL ✅ PostGIS ✅ MySQL ✅ MongoDB ✅Spatial indexing ✅ Spatial queries ✅ Database optimization ✅Geospatial data modeling GeoAI / Data Science ✅Python ✅TensorFlow ✅PyTorch ✅ Scikit-learn ✅Random Forest ✅XGBoost ✅ CNNs - Remote Sensing - Satellite Image Processing - Spatial Machine Learning - Predictive Modeling Visualization & Analytics ✅D3.js ✅ Plotly ✅ Power BI ✅Interactive dashboards ✅Spatial analytics ✅ Data visualization ✅ Cartographic design 💡 Projects I Can Help With • Custom Web GIS platforms • Parcel and land management systems • Utility & infrastructure mapping • Asset monitoring dashboards • Environmental monitoring systems • Real-estate location intelligence • Interactive property/parcel maps • Fleet and GPS tracking applications • Spatial data visualization • Site suitability analysis • Network and proximity analysis • Geocoding & address matching • Remote sensing workflows • Satellite imagery analysis • LiDAR processing • GeoAI / geospatial machine learning • GIS data automation • Spatial ETL pipelines • ArcGIS/QGIS to Web GIS migration • GeoServer/WMS/WFS implementations • Location-based APIs and applications 🔥 Why Clients Work With Me ✅GIS knowledge + software engineering in one person. You don't need to explain your spatial data to one developer and then explain the application to a separate GIS specialist. I understand both sides of the problem from coordinate systems, projections, spatial analysis, geoprocessing, and satellite data to databases, APIs, frontend architecture, deployment, and performance optimization. My focus is not simply to "put your data on a map." I build systems that help your users search, analyze, visualize, monitor, and make decisions from that data. Whether you already have an ArcGIS/QGIS workflow that needs to become a web application, a large spatial dataset that needs a proper database, or an idea for a completely new location-intelligence platform, I can help take it from GIS data → spatial backend → API → interactive application → production-ready solution. ⭐ 5+ years professional experience ⭐ 50+ projects delivered ⭐ GIS + Full-Stack + GeoAI expertise ⭐ Comfortable with fixed-price and milestone-based projects ⭐ Clear communication and reliable collaboration across time zones If you have a GIS workflow that is still manual, desktop-dependent, spreadsheet-driven, or difficult for non-GIS users to access, let's turn it into a system your team can actually use.

WebGIS & Remote Sensing Developer | Interactive Maps, Satellite Imagery Analysis & Python Automation Need an interactive web map, a spatial dashboard, or automation for your geospatial workflows? That's what I do. I'm Abdul-Hanan, a GIS & Geospatial Developer. I turn raw spatial data , shapefiles, satellite imagery, GPS logs, messy CSVs into tools people actually use. I build custom WebGIS dashboards with Leaflet.js, MapLibre, Mapbox GL, and Deck.gl for large datasets, design PostgreSQL/PostGIS databases with proper spatial indexing, and set up GeoServer for serving WMS/WFS layers with SLD styling and tile caching. On the automation side, I write Python/GDAL pipelines for batch geoprocessing, handle remote sensing tasks like NDVI and change detection, and build FastAPI backends that serve GeoJSON or vector tiles straight to your frontend. I also do routing and network analysis, and general data cleanup . fixing broken geometries, reprojecting CRS, merging messy datasets. If you've got rough or messy spatial data and need it turned into something that actually runs, that's the gap I fill.
