Freelancer Overview

I am an experienced AI Operations Specialist with a strong background in data annotation, labeling, and the preparation of high-quality training datasets for AI models, particularly in the field of 3D computer vision. My expertise includes annotating complex 3D datasets such as point clouds, LiDAR scans, depth maps, and multi-sensor data, as well as performing object detection, semantic segmentation, and object tracking. I have hands-on experience working with various sensor data, including LiDAR and RGB-D cameras, and am skilled in developing and applying taxonomy frameworks to ensure data consistency and accuracy. Additionally, I am committed to bias mitigation in data labeling and have collaborated with cross-functional teams to deliver fair and balanced datasets for AI training. My technical leadership and ability to mentor others further support my capability to contribute to high-impact AI projects.
