Labeling Experience

AI Data Trainer & Annotator — Scale AI

Scale AIImageObject Detection

I annotated and labeled large datasets for AI model development with a focus on image recognition, object detection, and text classification. I participated in evaluation tasks including prompt-response assessment and linguistic feedback on LLM content. I ensured quality compliance by collaborating closely with QA teams and maintaining a high standard of accuracy. • Labeled images and text for training computer vision and NLP models • Ranked prompt-response pairs to support dialogue system performance • Performed linguistic evaluations on AI-generated texts • Ensured data labeling quality accuracy exceeded 98%

Audio & Visual Data Annotator — Remotasks / Lionbridge AI

RemotasksVideoObject Detection

I annotated video frames and audio clips for sound event detection and object tracking to enhance machine learning capabilities. I used annotation tools to identify scenes, actions, and objects in visual datasets. I contributed to speech emotion recognition labeling and consistently met project quality and deadline requirements. • Tagged video scenes, objects, and actions for multiple annotation tasks • Labeled audio for sound event detection and emotion recognition • Helped train conversational AI using labeled datasets • Delivered consistent, high-quality annotations in agile, remote settings
