Labeling Experience

AI Data Annotator (Freelance / Remote)

ImageObject Detection

Annotated images for object detection, semantic segmentation, polygon, and bounding box tasks to support computer vision training. Applied consistent labeling conventions to ensure datasets were suitable for model learning. Performed related validation checks to maintain quality across high-throughput work. • Object detection and bounding box annotation • Semantic segmentation and polygon labeling • Quality control checks on labeled datasets • Adherence to project-specific style guides

Data Labeling Specialist (Outlier AI / Remote)

Text

Labeled large-scale text, image, and multimodal datasets to train and fine-tune large language models (LLMs). Reviewed and ranked AI-generated responses based on helpfulness, accuracy, and safety as part of model alignment. Maintained annotation accuracy above project quality thresholds while handling daily high-volume tasks. • Text and multimodal dataset labeling for LLM training • Response helpfulness/accuracy/safety ranking • Quality-threshold adherence in high-volume work • Edge-case escalation and guideline refinement support
