Labeling Experience

Advanced AI Data Trainer

ImageBounding Box

I contributed to high-accuracy text, audio, image, and video annotations for advanced AI and machine learning projects on multiple platforms. My role involved detailed 2D and 3D data annotation, including cuboid and bounding box creation for computer vision models, as well as audio transcription and annotation with attention to confidentiality. I adhered to strict quality assurance protocols, validated datasets, and collaborated with QA teams to ensure production-ready data. • Created bounding box and cuboid annotations for object detection, depth, and spatial awareness. • Performed audio and video annotation for classification and event/scene detection. • Flagged and corrected ambiguous or low-quality data to uphold dataset integrity. • Managed tasks via internal/proprietary annotation tools in a remote environment.
