Sebastián Arango

I am an Environmental & Geospatial Data Analyst with formal training in Environmental Engineering and a GIS specialization from UNIGIS – Universität Salzburg. I combine programming (Python, R, SQL) with GIS tools (ArcGIS, QGIS, Google Earth Engine) to transform environmental data into actionable insights.

I have built end-to-end data products including ETL pipelines, BI dashboards, interactive web maps, and a 3D bivariate climate–elevation map of Colombia, showcasing expertise in raster processing, spatial joins, and visualization for decision-making. I also developed a JavaScript/Leaflet web GIS demonstrating front-end spatial interaction and dynamic layer management.

My professional background includes roles in process engineering and education, where I managed operational and environmental datasets, optimized processes, and designed instructional strategies. I am detail-oriented, collaborative, and focused on applying spatial analytics to sustainability and resource management challenges.
