Need geospatial solutions that hold up at national scale, not just one-off map exports? I've spent 7+ years building GIS systems for Indonesia's Ministry of Public Works and Ministry of Communication, where the margin for error is slim and the data serves real policy decisions. Some things I've built and delivered: 1. A geospatial portal (SIGI PUPR) used by government planners across Indonesia for regional infrastructure development, from identifying housing locations for poverty eradication programs to prioritizing construction in underserved areas 2. Fiber optic network mapping across 34 provinces to support Indonesia's One Map Policy, including BTS tower placement optimization using spatial analysis and coverage overlay 3. A real-time WebGIS platform integrating live data streams for monitoring critical water resource infrastructure 4. A Sentinel-2 remote sensing pipeline using Python to detect and classify shrimp ponds in Malaysia with spectral indices (NDWI, MNDWI, AWEIsh, WRI) to automating what would otherwise take weeks of manual digitization 5. Hydrogeologic modeling to design an optimal groundwater monitoring well network, projecting flow patterns, contamination probability, and cost-effective placement My typical stack: Python (GeoPandas, GDAL, ArcPy), PostgreSQL/PostGIS, QGIS, ArcGIS Pro, Google Earth Engine, Leaflet.js, OpenLayers. I'm currently finishing my Master's in Information Technology at Universitas Indonesia, with research in NLP and topic modeling applied to disaster information. What you can expect working with me: I flag problems early, document everything so your team can maintain it after handoff, and I communicate in clear English, no disappearing acts, no ambiguous deliverables. If something doesn't make sense in your data, I'll tell you before it becomes your problem. Open to both short-term analysis tasks and longer-term WebGIS development projects.
