Turning multi-sensor data into decisions — from UAV-LiDAR point clouds and SAR imagery to Geo-AI models that map, predict, and protect landscapes across Nepal.

About Me

Who I Am

A Geomatics Engineer with hands-on experience in UAV-based data acquisition, LiDAR processing, and geospatial analytics — driven to bridge the gap between raw sensor data and actionable spatial insight through machine learning and advanced remote sensing techniques.

My work spans UAV mapping, bathymetric surveying, LiDAR feature extraction, flood-risk assessment, and multi-sensor spatial data integration for environmental and infrastructure applications across Nepal's diverse and challenging terrain.

Passionate about pushing the boundaries of earth observation and spatial intelligence — actively seeking research collaborations and opportunities where geospatial data science, Geo-AI, and cutting-edge remote sensing converge to create real-world impact.
