Đorđe M.

Senior GIS engineer with 12+ years turning large, messy spatial data into decision-ready systems. 100 projects, 16,000+ hours and $300K+ delivered on Upwork - 100% Job Success, Top Rated. Several client relationships have run continuously since 2015 and are still active today. I currently serve as ArcGIS Enterprise administrator for an international humanitarian organization, running Portal/Server, SQL Server enterprise geodatabases, Python automation and satellite-imagery pipelines used by roughly 8,000 field users worldwide. WORK AT SCALE - Renewable energy siting, USA (Terexis): screened the entire country four times over - 3,700 counties per pass, against the full US electrical grid. Multi-criteria model on slope, floodplain, wetlands and distance to substations and transmission lines, joined to county and state comptroller ownership records. Identified 100,000+ suitable parcels, delivered as thousands of ranked tables and KML files. 30+ power plants have been built from this analysis, with more under construction. - Telecom outside plant (Consolidated Infrastructure Group, as subconsultant on AT&T network): several hundred counties migrated from legacy CAD into enterprise geodatabases - 10,000+ manholes and nodes and 10,000+ conduits mapped, plus field-ready offline map packages. - Wildfire protection (University of Alberta): fire-protection planning and fire access road analysis across 1.74 million km2 of Alberta and Ontario, developed with a university researcher and later extended across the rest of Canada. - Environmental permitting, Australia (Element Ecology, ongoing): 300+ projects for Queensland and NSW clients - land-type reclassification, development permits and ecological impact assessment for government approval. - Global mining (Bloomberg): location and accessibility analysis for 1,000+ metal and mineral mines worldwide. - Aerial imagery processing (Urbansky): built the mosaicking, stitching and georeferencing workflow that turns balloon-captured imagery with GPS/INS ephemeris into a single seamless raster, DEM and orthophoto - around 10 Colorado towns processed end to end. - Land and real estate (Woodland Capital, ongoing): several hundred marketing maps for property sales plus property database management across Florida, Colorado, Tennessee, Alabama and Georgia, with parcel market analysis over dozens of counties on road, power and water access and future land use zoning. - Urban social analysis: five years mapping how unhoused populations move through Los Angeles relative to shelters, public kitchens, restrooms, showers and drinking water, used to target where services should expand. - Mineral exploration and cartography: 3D borehole and drill-line visualization for gold projects in Canada and India with custom Python plotting, plus several hundred topographic plans from survey, aerial and LiDAR data. WHAT I DO - ArcGIS Enterprise architecture and administration - Portal, Server, SQL Server enterprise geodatabases, row-level security, federated servers, service publishing - Python / ArcPy automation - Python toolboxes (.pyt), ModelBuilder pipelines and custom geoprocessing tools that run unattended at national scale - Site selection and suitability modeling - multi-criteria parcel screening for solar, wind, telecom and real estate - Satellite imagery processing - automated pipelines for WorldView-1/2/3, Airbus PNEO, SkySat/Planet and Sentinel-2: pansharpening, orthorectification, color correction, Cloud Optimized GeoTIFF output - Remote sensing analysis - NDVI/dNDVI change detection, land-cover and FLUCCS classification, clearcut and new-construction detection - Photogrammetry and orthomosaics - stitching, color correction, georeferencing, DEM and orthophoto generation - Legacy CAD to GIS migration - DWG/DXF into clean, topologically correct geodatabases - Web GIS and map services - ArcGIS Online, GeoServer WMS/WFS with SLD styling, COG optimization, offline field packages - Data integration - joining assessor, comptroller and ownership records to spatial data; web scraping for spatial datasets - Terrain and hydrology - TIN/DEM modeling, contours, breaklines, flood risk and topographic analysis - Custom cartography - print-ready maps, atlases, thematic and marketing maps TOOLS: ArcGIS Pro, ArcGIS Enterprise (Portal/Server), ArcGIS Online, ArcPy, Python, QGIS, GDAL, GeoServer, SQL Server, FME, AutoCAD Civil 3D, MapInfo, Copernicus/Sentinel Hub, Claude and Claude Code FORMATS: Shapefile, GeoJSON, KML/KMZ, GPKG, File Geodatabase, DWG/DXF, GeoTIFF/COG, MID/MIF, CSV, PDF map exports - raster, vector and CAD INDUSTRIES: renewable energy, telecom and fiber, real estate and land, mining, environmental and humanitarian, utilities, government, academia I also teach: two years as private tutor to a UNIGIS Salzburg student, who completed his degree last month. Send me your data and your deadline - a single map, a stalled dataset, or a full automated pipeline. A solution is on the way!
