Building my career in geospatial technology.

I am a Geomatics Engineer with hands-on experience across land surveying, Geographic Information Systems (GIS), remote sensing, and geospatial data analysis. My fieldwork spans GNSS/GPS, DGPS, RTK, and static GNSS positioning, cadastral and topographical surveying, total station operations, and levelling, complemented by survey camp experience in hydropower feasibility, and road and bridge projects.

Alongside fieldwork, I apply Python, machine learning, and WebGIS development to process, analyse, and communicate geospatial data — most notably through my final year research estimating biomass and carbon stock using satellite imagery and remote sensing techniques. I am committed to applying modern geospatial technologies to surveying, infrastructure planning, environmental monitoring, and spatial decision-making, and I am actively seeking opportunities to contribute to geospatial projects where accurate field data and rigorous analysis drive better outcomes.
