I build production geospatial web platforms, real-time 3D maps, and spatial data stories in the browser using React, Three.js, WebGL, MapLibre/Mapbox, and PostGIS.
Top Rated · 100% Job Success · $70K+ earned on Upwork · 18+ years across GIS, cartography, and web development.
I turn complex spatial data into clear, interactive systems that combine technical rigour, performance discipline, and visual storytelling.
Selected production work:
• Environmental Intelligence Platform - multi-million entity geospatial SaaS (MapLibre, PMTiles, PostgreSQL, GraphQL)
• 3D Reef Health - 15+ month marine spatial platform (MapLibre, Three.js, production hosting)
• Inner Fire - real-time WebGL seismic globe (React 19, instanced rendering, live USGS feed)
• IIB-recognised visual projects + #100DayMapChallenge (100 consecutive public geospatial builds)
I work end-to-end: data preparation, architecture, implementation, optimization, and handoff.
Typical engagements:
• Interactive map modules and story maps (Mapbox/MapLibre, Wix/CMS embeds)
• Real-time 3D spatial interfaces (Three.js / R3F / WebGL)
• Geospatial dashboards and climate/environment platforms
• Map performance and UX audits (consultation or fixed scope)
Stack:
• Frontend: React, TypeScript, Three.js, WebGL, GLSL, MapLibre GL / Mapbox GL
• Data/GIS: PostGIS, PostgreSQL, QGIS, GDAL, PMTiles
• Focus: digital twins, environmental and climate data, immersive spatial interfaces
I am selective about projects where spatial accuracy, performance, and visual quality all matter.

🌍 Geospatial Intelligence Engineer | Advanced GIS Automation | EU-Scale Land Monitoring & Urban Planning Expert
I specialize in transforming large, complex geospatial datasets into high-accuracy, decision-ready intelligence through advanced GIS automation, remote sensing, spatial data engineering, and high-performance geoprocessing pipelines. My expertise is built on delivering EU-level land monitoring, urban planning infrastructures, and cadastral/topographic data integrations at a scale rarely mastered by a single specialist.
🚀 What I Bring to Your Project (based strictly on proven results)
🇪🇺 EU-Wide Remote Sensing & Photointerpretation — LUCAS Grid 2025
✔ Processed 350,000+ land cover sampling points across all EU member states
✔ Achieved 93% classification accuracy, following EU-standardized methodologies
✔ Applied rigorous QA/QC for consistent, audit-ready land monitoring datasets
✔ Delivered continent-scale photointerpretation aligned to advanced stratification criteria
🏙️ Advanced GIS for Urban Planning & Territorial Development
✔ Coordinated 24 complex GIS projects, covering ~480 km² of territorial planning zones
✔ Created and integrated 24 multi-layer geodatabases (20–30 layers each)
✔ Performed zoning, spatial diagnostics, and regulatory mapping at administrative scale
✔ Developed 15 automated geoprocessing workflows using Python + PostGIS → 60% faster delivery
✔ Built 20+ ModelBuilder tools for zoning, boundaries, and planning workflows
✔ Delivered 500+ professional map sheets, with 50–100 layers each, optimized through custom Python scripts
✔ Validated 10,000–20,000 spatial records per commune, increasing dataset reliability by ~10%
📡 Topographic & Cadastral Data Engineering
✔ Conducted land surveys for ~60 km² across 3 communes, covering 40,000 cadastral plots
✔ Integrated GPS / theodolite / electronic level data into GIS & AutoCAD
✔ Created OCPI-compliant cadastral plans and topographic deliverables
✔ Streamlined survey→GIS workflows, reducing processing time by ~20%
🔧 High-End Technical Stack (exact from CV, optimized for Upwork search)
GIS & Remote Sensing: QGIS, ArcGIS Pro, ArcMap, ModelBuilder, Google Earth Engine, Photointerpretation
Automation & Data Engineering: Python (geopandas, rasterio, shapely), PostgreSQL / PostGIS, SQL, GitHub
CAD & Surveying: AutoCAD, CadGen, GPS processing, theodolite workflows
Spatial Analysis: Raster/Vektor geoprocessing, predictive analysis, hazard mapping, multi-criteria evaluation
🎯 How I Work & The Value I Deliver
Clients who work with me get more than maps — they get scalable, validated geospatial intelligence systems, built with scientific precision and engineering efficiency. My experience spans:
large public-administration datasets
city-scale and regional-scale planning
high-accuracy remote sensing
statistical + spatial modeling for territorial planning
automated pipelines for repeatable geoprocessing
full-cycle GIS support: survey → processing → analysis → maps → compliance
Every project is delivered with audit-ready data, reproducible workflows, and professional cartography.
🧠 Education & Specialization
Master’s in Natural Hazards & Territorial Planning (GIS-focused) — advanced spatial modeling, hazard mapping, geodatabases
Bachelor’s in Territorial Planning — renewable energy spatial evaluation, cartography, field data acquisition
Advanced Training:
GIS Automation, Spatial Data Science, Machine Learning in GIS, ArcGIS Pro advanced tools, PostGIS databases, AI-enhanced raster analytics
💬 If you need a senior-level GIS specialist capable of handling massive datasets, complex automation, EU-level methodology, or high-stakes urban planning workflows — I can deliver at the highest technical standard.
