What I'm looking for

I’m looking for data-labeling and geospatial roles where accuracy and guideline compliance matter. I want to apply my civil engineering and photogrammetry/drone mapping skills to produce quality-checked training data for AI and mapping systems, working independently or in a team.

I’m a detail-oriented data annotator currently labeling roof geometry on Nearmap aerial imagery at CloudFactory, using strict annotation guidelines to deliver high-accuracy, high-throughput labeled datasets. With a civil engineering foundation and hands-on geospatial expertise, I interpret complex roof shapes, obstructions, and structural edge cases so the geometry in training data matches real-world building structures.

Alongside annotation work, I’ve supported municipal infrastructure projects as a Civil Sub-Engineer, including cost estimations, Bills of Quantities (BOQ), site supervision, and permit/contractor workflows using EBPS and E-Bidding System. I also bring project experience in photogrammetry, drone mapping, 3D laser scanning, and georeferenced 3D modeling from the Swoyambhunath collaborative project, plus topographical survey and DPR assistance for the Chaange Bridge.
