About me
I am currently pursuing an MSc in the field of GIS and Remote Sensing and am based in Germany. I turn satellite, spatial and water-chemistry data into maps and analysis you can defend in a report, a paper or a client meeting. What I do: land cover classification & change detection, NDVI/vegetation indices, georeferencing, DEM/terrain analysis, publication-quality cartography, PHREEQC geochemical modelling, and Piper/Durov/Stiff/Schoeller diagrams. Tools: QGIS, ArcGIS Pro, SNAP, PHREEQC, Python. I work in CET and reply the same working day.... Read more

Graduate Research Assistant

University of Moratuwa • Full-time

Aug 2025 - Jan 2026 • 5 mos

Processed Sentinel-1 SAR and Sentinel-2 optical satellite imagery, including full SNAP preprocessing and multi-modal data fusion. Extracted spectral indices, radar backscatter, and GLCM texture features, then applied SPCA for dimensionality reduction. Performed land-use/land-cover classification using Random Forest, SVM, and Maximum Likelihood, with full accuracy assessment. Conducted GIS spatial and temporal analysis, including Mann-Kendall trends, Moran's I, Getis-Ord Gi* hotspots, and buffer-zone analysis. Produced publication-quality maps, charts, and fully referenced academic reports.
