I turn messy environmental, agricultural and geospatial data into decisions. Not just maps and shapefiles, the forecast, the dashboard and the answer your team can act on. I am a Data Scientist and Forest Engineer with 10+ years of experience. I currently lead the Data Intelligence area for the Planning Advisory Department at IDR-Paraná, where my pipelines support 399 municipalities and inform an agricultural and forestry sector worth billions. In practice that means I do four things most GIS freelancers do not do together: Geospatial data engineering. Production Python + PostGIS pipelines that pull multi-source data (satellite, census, trade, land prices, field data) into clean, reproducible datasets. Scheduled and tested with GitHub Actions, not one-off scripts. Machine learning on spatial data. scikit-learn and PyTorch models for time-series forecasting, clustering and segmentation, and collaborative filtering. The “what does this mean and what happens next” layer, not just the map. Decision dashboards. Interactive Plotly/Dash and Power BI dashboards that stakeholders actually use to decide. I built Datageo Paraná, a public platform with 10 interactive dashboards spanning 30+ years of data and 400+ products (VBP, census, ComexStat, employment, land prices, forestry prices). Domain depth. Forestry, agribusiness, sustainability and public-sector analytics. I have led FSC- and NR-31-compliant operations across multi-million-hectare projects, so I understand the data and the decisions behind it. What you get when you hire me: a clear scope up front, fast and direct communication, a documented methodology, original analysis (never recycled or plagiarized), and a full handoff of the maps, the validated pipeline and the code. You own everything at the end. Tools: Python, PostGIS / PostgreSQL, QGIS, scikit-learn, PyTorch, Plotly/Dash, Power BI, Supabase, GitHub Actions, GDAL/GeoPandas/Shapely/rasterio, SQL. Good fit if you need: satellite / remote-sensing analysis, geospatial web scraping and data acquisition, spatial data pipelines, forecasting or segmentation on geographic data, interactive geo dashboards, or forestry / agribusiness / environmental decision analytics. If you have geographic data and a decision to make, message me. I will tell you honestly whether I am the right fit and what the smallest useful first step looks like.
