Struggling to make sense of complex geospatial data, from 3D city models and LiDAR to river networks and seabed surveys? I build fast, interactive CesiumJS and web-mapping applications, using AI-powered automation to turn raw spatial data into clear tools your team can explore, measure, and act on. Top Rated | 100% Job Success | 5.0 stars from 16 clients | 7+ years in GIS | 41 jobs, 1,900+ hours PROVEN RESULTS - 7 clients have hired me again, including Cesium viewer work that ran from February 2025 to July 2026. - Shipped a KMZ-upload web app MVP (interactive map, login, comments) in 3 weeks. - Built a real-time earthwork tracking application in Cesium for a construction client. WHAT I BUILD Web mapping and 3D visualization - Interactive 2D/3D web maps and viewers with CesiumJS, WebGL, Three.js, Leaflet, OpenLayers, Mapbox and React - Terrain, imagery, 3D Tiles, 3D buildings and CityGML models for urban planning and digital twin projects - Measurement, heat map and analysis tools built directly into the viewer Hydrological and seabed data - Visualization and analysis of bathymetry and seabed terrain surfaces - River, watershed and water-network mapping - Depth, elevation and terrain analysis, displayed in 3D AI and automation for geospatial work - Automated spatial data pipelines that clean, convert, and process large datasets - AI-assisted analysis of imagery, drone and LiDAR data - AI assistants inside map apps, so users can search, filter, and query spatial data in plain language Spatial data and backend - PostgreSQL/PostGIS databases, GeoServer, ASP.NET Core APIs - GIS analysis and remote sensing with ArcGIS, ArcGIS Online and QGIS - Data conversion and ETL: GeoJSON, Shapefile, KML/KMZ, GeoTIFF, FME Drone and LiDAR - Point-cloud and drone data processing and visualization (Potree) Cloud - AWS deployment (EC2, RDS, S3, Lambda) with CI/CD INDUSTRIES Urban planning, surveying and mapping, construction, environmental monitoring, water resources, marine and coastal, real estate, utilities, agriculture. HOW IT WORKS 1. Message me your data type (LiDAR, bathymetry, GeoJSON, drone imagery...), your goal and your timeline. 2. Within 24 hours you get a scoped approach and an estimate. 3. I build and share working demos along the way, so there are no surprises at delivery. Not sure where to start? Book a $20, 30-minute consultation and we'll map out your project together.
