Got a maps or geospatial problem? I've likely already built a solution for it. I'm a GIS Full Stack Developer with 10+ years of experience building AI-powered geospatial applications — from satellite-based deforestation detection tools used by agricultural companies for EUDR compliance, to real-time pipeline monitoring dashboards with SCADA integration, to LLM-integrated web GIS platforms. I don't just build maps — I build systems that turn satellite and spatial data into business decisions. What I work with: Web GIS: OpenLayers, MapBox, Leaflet, GeoServer, PostGIS AI/ML: Random Forest, SVM, Gradient Boosting, Deep Learning for satellite imagery ESRI Full Stack: ArcGIS Online, ArcGIS Server, ArcGIS Runtime (.NET, QT), Web AppBuilder Open Source: QGIS, GDAL, GeoPandas, Shapely Backend: Python (Flask/FastAPI), .NET Core, REST APIs Mobile: ArcGIS Runtime Xamarin, QT Recent work includes: Built an automated EUDR compliance tool analyzing satellite imagery for supply chain deforestation risk Developed a live pipeline monitoring dashboard with real-time GIS mapping Created a free web-based GIS editor used by professionals and government agencies globally Integrated locally-run LLM models into an OpenLayers web GIS application I've worked with Bayer Crop Science, IWMI (Sri Lanka), and multiple Upwork clients across oil & gas, agriculture, waste management, and e-governance. If your project involves maps, satellite data, spatial analysis, or location intelligence — let's talk.

I sit at the intersection of environmental science and geospatial engineering combining 9+ years of Earth system research with hands-on expertise in building production-grade GIS platforms, spatial data pipelines, and real-time environmental monitoring systems. 🌍 Geospatial Development & Web GIS: I design and deploy end-to-end geospatial solutions using industry-standard spatial infrastructure. My stack includes GeoServer and MapServer for OGC-compliant spatial services (WMS, WFS, WCS, WPS), ArcGIS Server / ArcGIS Enterprise with custom GP Services, and ArcGIS Online / Portal for enterprise deployments. On the frontend, I build dynamic, map-centric web applications using React.js and Node.js, integrating Leaflet, OpenLayers, ArcGIS JS API, and Mapbox GL JS to deliver polished, responsive interfaces. I consume and publish REST APIs and GeoJSON/OGC services fluently, and architect scalable spatial backends that connect databases (PostGIS, SDE), middleware, and live remote sensing feeds. 🛰️ Remote Sensing, GEE & Cloud Geospatial: I am deeply proficient in Google Earth Engine (GEE) — both the JavaScript and Python APIs — for large-scale satellite analysis, custom indices, time series extraction, and asset export workflows. I have worked extensively with Sentinel-1/2, Landsat, MODIS, MISR, and CloudSat imagery for flood mapping, LULC change detection, vegetation analysis, and atmospheric retrievals. I also leverage GEE API services to feed live computed outputs directly into web dashboards and geoportals. 🌡️ Climate, Atmospheric Science & Air Quality My research background spans climate forecasting, air quality assessment, and emissions analysis using model datasets including ERA5, MERRA-2, CAMS, and CHIRPS. I develop emission inventories, airshed-level management frameworks, hot-spot mapping workflows, and sector-specific energy demand forecasts. I have hands-on experience with ionospheric data, PM2.5 retrieval from aerosol constituents, and multi-variable atmospheric visualization pipelines. Programming & Data Engineering I code production-ready tools in Python, R, MATLAB, and JavaScript, with strong capabilities in spatial data mining, advanced visualization (Chart.js, Plotly, Matplotlib), and predictive modeling. I have a proven track record converting legacy Fortran, IDL, and Mathematica codebases into modern, maintainable Python frameworks — a rare but highly valuable skill for organizations modernizing their scientific infrastructure. Dashboards, Portals & Decision Support Systems I deliver custom geospatial dashboards and monitoring portals — from disaster management platforms and flood monitoring systems to air quality indices and renewable energy assessment tools — using ArcGIS Dashboards, ArcGIS Experience Builder, Power BI, and bespoke React-based interfaces. Every solution is built with real operational users in mind: clean UI, live data integration, and meaningful spatial storytelling. What sets me apart is the rare combination of scientific rigor and engineering execution. I don't just analyze environmental data — I build the systems that make that analysis accessible, scalable, and actionable for decision-makers on the ground. Open to projects in: Web GIS development · Remote sensing automation · Climate data pipelines · Environmental monitoring platforms · GeoServer/MapServer deployment · ArcGIS Enterprise solutions · GEE scripting & API integration

Hello all, I Build custom mapping applications that turn data into something people can understand — searchable, filterable, auto-updating maps connected to the popular tools you already use (Airtable, Google Sheets, your own database). Recent work: • A live travel-data map that pulls daily updates from Airtable and renders them on a custom Google Maps interface — no manual re-publishing, the map stays current. check at - travel.lbd.ventures • A 3D building visualizer that lets users import and place 3D models directly onto Google Maps at real-world scale. -check at - airdome.web.app • A risk-mapping tool visualizing methane well data across the US for environmental assessment. - methane-risk-mapping.web.app • A location-search app for public amenities (parks) with live area-based filtering. Beyond maps, I'm a full-stack engineer — 8 years building web, mobile (iOS/Android), and IoT systems, including a Raspberry Pi-based access control system. So if your "map project" also needs a backend, auth, a mobile companion app, or hardware integration, I can own the whole thing instead of you stitching together three freelancers. Stack: JavaScript/TypeScript, React, Google Maps & Places API, Airtable API, Python, Node, GCP/AWS, Swift, Kotlin. Portfolio: sanjaygoswami.web.app
