Profile Summary

GIS and Remote Sensing Specialist and Data Analyst with a BSc (Honours) in Fisheries and Marine Sciences from the University of Ruhuna. I help researchers, graduate students, and organizations turn spatial and statistical data into publication-ready analysis from NDVI/NDWI time-series and shoreline change detection to fisheries stock assessment and ecological modeling. Core tools: QGIS, ArcGIS Pro, Google Earth Engine, Python (GeoPandas, Shapely, Matplotlib), R (STL decomposition, Mann-Kendall trend tests, BFAST), and SPSS for statistical analysis. Recent work includes coastal shoreline change analysis using multi-decade Landsat imagery, mountain ecosystem time-series analysis across elevation gradients, and methodology/statistical support for a peer-reviewed skipjack tuna manuscript (including GAM modeling and reviewer response). I deliver clean, reproducible workflows with clear documentation ideal for thesis chapters, manuscript statistics, GIS deliverables, or standalone data analysis reports.
