Muhammad A.

GIS Developer who builds web maps and spatial data platforms clients actually use. 85+ Upwork contracts, Top Rated, 100% Job Success, $70K+ earned. Mapbox GL, Leaflet, MapLibre, React/Angular, PostGIS, Python, ArcGIS and QGIS. 12+ years. Most GIS projects need more than one skill: someone to clean and analyze the data, store it in a spatial database, publish it as services, and build the map people actually use. I handle that whole chain, so you work with one specialist instead of coordinating an analyst, a database engineer and a web developer. WHAT I CAN DO FOR YOU • WebGIS & web map development (my core work) Interactive web maps, property search portals, service-area and disaster-reporting platforms and geospatial dashboards with Mapbox GL, MapLibre, Leaflet, OpenLayers, deck.gl and Cesium, in React or Angular, with Django or FastAPI backends. Esri: ArcGIS JavaScript API, ArcGIS Online, Experience Builder, Field Maps, Dashboards and StoryMaps. Recent Upwork work: YardReach service-area visualization (Mapbox), AerialGIS real estate portal (React, Django, PostGIS, rated 5.0), Fire Risk Assessment mapping, and an Angular/Leaflet grid-analysis app (rated 5.0). • Spatial analysis & GIS data analysis ArcGIS Pro and QGIS for geoprocessing, data cleaning, thematic mapping and map production. Recent work: fire-risk assessment, flood-zone screening for property search, service-area mapping and community health mapping. Vector and raster data, including Shapefile, GeoJSON and GeoTIFF. • Spatial databases & large geospatial datasets PostgreSQL/PostGIS and Oracle Spatial: database design, spatial indexing, query optimization and data migration. I have worked on US property datasets with billions of records, where fast spatial queries are what keep the application usable. • GIS automation & data pipelines Python (GeoPandas, GDAL, Rasterio, Shapely), FME and ETL pipelines; GeoServer and MapServer for WMS/WFS services; Docker and AWS deployment. • GeoAI & site suitability Site selection and suitability scoring that combines many spatial layers to rank locations, feature extraction from imagery, land-cover classification, and predictive risk mapping for wildfire and flood. Ask me about this if your project needs analysis on top of the map. SELECTED UPWORK PROJECTS • Mapbox service-area visualization for a lawn-care platform • AerialGIS real estate GIS portal (React, Django, PostGIS) — 5.0 review • Angular + Leaflet grid-analysis WebGIS — 5.0 review • Fire-risk assessment mapping • Real estate WebGIS property search portal (Mapbox, React) • UK property search with flood-zone analysis (ArcGIS JavaScript API) • Python application for GIS polygon generation and mapping BACKGROUND BEng Software Engineering with GIS and Remote Sensing, NUST. Founder and CEO of Jugrafiya, a GIS software company working with real estate, telecom, utilities, oil and gas, agriculture and tourism clients. Upwork clients describe me as knowledgeable, responsive and a clear communicator. Send me a message with your data (format and size), the tools you already use and the result you need: a map application, an analysis, a database, or an automated pipeline. I'll reply with a suggested approach and the questions that matter.
