I help businesses transform geospatial data into actionable insights through GIS, spatial analysis, interactive mapping, and Python automation.
My work includes:
• Parcel and land analysis
• Spatial relationship modeling
• Drive-time / accessibility analysis
• Interactive maps and dashboards
• GIS workflow automation
• Large-scale geospatial data processing
Recently, I developed a GIS automation tool for large-scale parcel and road relationship analysis in Australia. The system supports identifying frontage roads, parcel orientation, corner lots, and multi-road adjacency through rule-based spatial analysis workflows.
The solution was designed for practical use in real workflows, and packaged as a standalone application with batch processing and configurable parameters for non-technical users.
Core expertise:
* Spatial analysis and GIS data processing
* Map-based analysis and parcel-level studies
* Road-network and accessibility analysis
* Python-based geospatial automation
* Data preparation for mapping and reporting workflows
Tools & technologies:
Python, GeoPandas, QGIS, ArcGIS Pro, PostGIS, Pandas, Shapely, Jupyter Notebook
I also have experience building more advanced spatial rule-based systems that bridge traditional GIS analysis with emerging geospatial intelligence workflows (GeoAI concepts), especially in structured spatial relationship modeling.
