About
I am a geomatics engineer working at the intersection of spatial data, community knowledge, and practical technology. My work moves between database architecture, WebGIS, OpenStreetMap, UAV imagery, LiDAR, remote sensing, and the people who use those systems.
Today I lead the mapping department at Gallimaps, contribute to open geospatial infrastructure with OSGeo Nepal, and continue growing a global community of open mappers through training and mentorship.

Experience
From city navigation to humanitarian datasets, I work across the full geospatial chain: collection, quality, storage, analysis, delivery, and training.
Leading mapping operations, spatial data quality, geospatial workflows, and the team behind reliable local navigation data.
Designing database and backend architecture for OSMSG, an open-source platform that processes and analyzes large OpenStreetMap datasets.
Managing spatial databases and pipelines, maintaining WebGIS products, and supporting imagery-based urban mapping.
Contributing UAV and GIS support when needed, including field workflows connected to disaster response and resilience.
Training new mappers, mentoring community leaders, and improving open geospatial data for humanitarian and climate-resilience work.
Projects
Selected geospatial projects from my CV, connecting environmental risk, point clouds, routing, open data, and production mapping systems.
Built a national cropland heat-risk workflow using MODIS LST, NDVI, evapotranspiration, Sentinel-1 moisture stress, ESA WorldCover, and FAO WaPOR AETI outputs for observed 2025 risk and a trend-based 2026 heat-hazard scenario.
Processed mobile and airborne LiDAR point clouds, applied allometric models, and visualized forest biomass and carbon stock for subtropical forest analysis.
Designed database and backend workflows for OSMSG, processing large OSM datasets and supporting repeatable geospatial analysis through OSGeo Nepal.
Explored practical routing, interactive map interfaces, and multi-source navigation workflows for clearer local movement and decision-making.
Created dynamic map layers using open data, weather, earthquake information, amenities, and spatial storytelling for better public-facing geospatial communication.
Mapped utility services with layer controls, attribute popups, accessible styling, and infrastructure suitability analysis for the 28 Kilo area.
Field notes
A visual record of the systems I have built, communities I have learned from, and knowledge I have shared.
Three intensive days working with DJI Matrice 350 RTK platforms, P1 and L2 sensors, and the DJI Air 3S. The training connected flight operations and geospatial data collection directly to faster, better-informed disaster response.
With FAO Nepal and Geosat Solutions Inc.
Facilitated a two-day Mapillary training with YouthMappers FWU under Women in Open Mapping: Asia Navigators. Students moved from learning the platform to creating meaningful street-level data and stepping into the open mapping community.
At CIPA Nepal Heritage School in Pokhara, I followed the complete heritage-documentation workflow using TLS and SLAM LiDAR, UAVs, DSLR photogrammetry, FARO Scene, Agisoft Metashape, and CloudCompare. The scholarship experience strengthened both my technical practice and my commitment to preserving Nepal’s cultural heritage.
Joined the global OpenStreetMap community to exchange ideas, host sessions, present my poster, and celebrate HOT’s fifteenth anniversary. It was a vivid reminder that open mapping is powered as much by relationships as it is by data.
Studied neural networks, activation functions, and backpropagation to extend machine-learning thinking into spatial pattern recognition and image-based geospatial analysis.
Strengthened core Python fluency for more complex data processing, automation, and geospatial development work.
Led an OpenStreetMap session during an ILIKA and GES collaboration, followed by hands-on community mapping. The event translated curiosity into practical contributions to open geospatial data.
A smart-routing web application exploring how pathfinding, multiple data sources, and thoughtful map interfaces can create a clearer navigation experience.

Worked with Topcon survey-processing software and LiDAR technology through a collaborative program involving Kathmandu University, LMTC, and the University of Southern Queensland.
Helped bring together a team around geospatial innovation, climate action, digital governance, sustainable cities, and disaster-risk reduction through Women in Geospatial Nepal.
An exploration of dynamic layers, real-time weather and earthquake data, nearby amenities, and interactive spatial storytelling with Leaflet and GeoJSON.

Open the toolExplored GIS, remote sensing, image analysis, spectral indices, and the use of Earth observation data to monitor air quality.
Received Youth Innovation Lab’s OSM Grant Supporting Women Leaders and contributed 102 hours mapping and validating buildings, roads, rivers, open spaces, and other essential infrastructure in at-risk areas of Nepal.
Team Analytica placed second with an accessible utility map for the 28 Kilo area. I helped build interactive layers and popups, identify infrastructure gaps, and develop a suitability view for transformer malfunction planning.
View the projectTrained participants across the open mapping workflow, including OpenStreetMap, JOSM, Overpass Turbo, and uMap, with community partners across Nepal and the Asia-Pacific region.
Introduced Grade 9 and 10 students at Bal Vidhya Mandir Secondary School to how maps are made, read, and used to understand the world around them.
Served as rapporteur during two days of engineering, technology, and innovation discussions hosted by AMES at Kathmandu University.
Completed four days of blended training in GIS, remote sensing, land-cover analysis, data visualization, and disaster preparedness with SERVIR, ICIMOD, NASA, and USAID.
My first hackathon ended with Team Thoplo securing first runner-up for a field-mapping task-splitting algorithm. Two demanding days with NAXA, Kathmandu Living Labs, NGES, and HOT turned hard work into an early lesson in collaboration and geospatial problem-solving.
