Freelancer Overview

Marine Biologist and Environmental Data Analyst with an MSc from the Università degli Studi di Napoli Federico II and seven years of combined academic and professional experience in large-scale geospatial and ecological data analysis. My work consistently involves interpreting, validating, and structuring complex datasets derived from satellite imagery (Sentinel-2, Landsat-8), species distribution models, and fisheries monitoring systems — the same precision and domain expertise that underpins high-quality AI training data. I specialize in remote sensing, GIS analysis (QGIS, Google Earth Engine), and environmental modeling (MaxNet, R/tidyverse), with applied experience in land cover classification, change detection, and data quality assurance across multi-temporal datasets. My scientific background allows me to contribute meaningfully to annotation projects requiring subject-matter expertise in earth observation, ecology, marine science, and environmental systems, going beyond mechanical labeling to ensure data that is accurate, contextually grounded, and model-ready.
