CVATTextClassification

As a freelance AI Data Annotator and Data Labeling Specialist, I annotated and labeled datasets used to train machine learning and AI models. My work involved reviewing and categorizing large amounts of text and language data for quality assurance and accurate labeling. I closely followed annotation guidelines to ensure consistency and help reduce bias in training datasets. • Labeled and structured text datasets for natural language processing tasks. • Performed quality assurance checks to ensure high standards in AI training pipelines. • Collaborated with project teams to refine annotation instructions. • Maintained detailed workflow documentation and resolved ambiguous data cases.

Remotasks3D SensorCuboid

As an AI Data Annotator at Remotasks, I worked on annotating LiDAR and 3D point cloud data using cuboids to enable object detection and tracking. I also annotated large-scale image, text, and video datasets for machine learning model training, focusing on accuracy and consistency. I applied various annotation techniques for computer vision and NLP projects. • Used CVAT and other platforms to annotate and review diverse datasets. • Performed bounding box, semantic segmentation, and keypoint labeling on image and video data. • Conducted entity recognition tasks for natural language datasets. • Ensured data quality through peer reviews and compliance with privacy protocols.
