Freelancer Overview

I have extensive experience in data collection, annotation, and management, primarily within cadastral, geographic information systems (GIS), and civil engineering domains. My background includes coordinating national data operations, overseeing the collection, processing, and quality control of large-scale spatial and property datasets, and training teams in data labeling and mapping. I am proficient in tools such as AutoCAD Civil 3D, ArcGIS, QGIS, MapInfo, and PostgreSQL/PostGIS, and have hands-on experience with data management platforms like KoboToolbox and Microsoft Office Suite. My work has involved leading projects that required meticulous data annotation and validation for land evaluation, infrastructure, and urban planning, ensuring high data accuracy and integrity. I am comfortable working with multilingual datasets and am skilled in Python and web programming, which allows me to support automation and process optimization in data workflows.
