Freelancer Overview

I have experience in AI training data and data annotation through remote projects involving voice data and 3D LiDAR datasets. As a Voice Data Specialist at Voices.com, I recorded, validated, and annotated Indonesian voice data to improve speech recognition models and evaluated AI voice outputs for pronunciation, intonation, and fluency. I also worked as a 3D LiDAR Labeler at Nexter, performing point cloud annotation using 3D bounding boxes for computer vision datasets while ensuring high labeling accuracy and quality standards. With a background in Informatics Engineering and strong attention to detail, I am committed to producing high-quality training data that supports reliable AI systems.
