Mostafa B.

I build geospatial web and mobile applications, leverage Python and automation tools to streamline spatial data processing, and turn complex datasets into powerful, easy-to-use solutions. Why Clients Choose Me Web GIS development is my core expertise. I specialize in building custom mapping solutions, interactive GIS dashboards, location-based mobile apps, and full-stack geospatial platforms that are fast, scalable, and production-ready. Whether you need a 2D web mapping application, an immersive 3D visualization platform, a cross-platform mobile GIS app, a fleet routing and logistics system, or a complete spatial data pipeline with automated workflows, I deliver end-to-end — from database design and API architecture to frontend and mobile deployment. I don't just put pins on a map. I build complete GIS solutions with intuitive interfaces, high-performance backends, automated data orchestration, and clean workflows that hold up at scale. Services I Offer Custom web map development with Leaflet.js, OpenLayers, and Mapbox. Cross-platform mobile GIS applications using React Native. 3D geospatial visualization using CesiumJS and Potree for point cloud rendering. RESTful API design and development for geospatial services. Spatial database design and optimization with PostgreSQL and PostGIS. GIS dashboard development with real-time data integration. Automated geospatial data pipelines and ETL workflows using Apache Airflow. Route optimization and logistics platforms with custom constraint handling. Geodata processing using GDAL, OGR, and Python automation. GeoJSON, Shapefile, GeoTIFF, and LAS/LAZ data conversion and processing.
