🌟 New to freelancing — not new to delivering results. You just found a rare gem. 🌟 📍 You give me messy spatial data — I give you clean, useful maps and automated workflows. Fast. 💼 What I Do I help small teams and solo operators turn geospatial chaos into clarity. If your data is scattered, unstructured, or you just don’t know how to map it — I fix that using Python and open-source tools. You don’t need a full GIS department. You need one person who gets it done. 🎯 What You Get - Clear, custom maps — static or interactive - Automated workflows that save hours of manual work - Spatial insights that actually support decisions - Clean, organized data ready for reports, Power BI, or dashboards - No GIS jargon unless you want it 🧰 How I Do It I’ve spent 6 years solving messy data problems for corporates — scraping websites, cleaning spreadsheets, building dashboards, managing databases, and analyzing spatial layers. Now I focus on GIS and Python automation for lean, results-driven teams. 🛠 Tools I use daily: - Python (GeoPandas, Pandas, Shapely, Rasterio, Folium) - Spatial formats (GeoJSON, Shapefiles, CSVs) - Map projections, CRS handling, georeferencing - Workflow automation - Integration with Power BI, Google Sheets, or your existing systems 🤝 Who I Work Best With - NGOs needing practical mapping support - Researchers handling location-based data - Startups or teams who need results, not overhead - Anyone stuck with spatial data and no one to help P.S. My to-do skill set is not only limited to GIS. Want to know more? Just book a call
