Freelancer Overview

I am a detail-oriented Computer Science graduate with hands-on experience in computer vision data annotation and salient image captioning for AI training datasets. My work as an AI Data Annotator and Salient Caption Specialist has equipped me with strong skills in object detection, bounding box labeling, and coordinate-based object marking, ensuring high-quality and guideline-compliant datasets for computer vision and multimodal AI systems. I am adept at producing precise visual descriptions and context-focused captions, supporting large-scale dataset preparation on remote annotation platforms. My strengths include a keen eye for visual detail, strong pattern recognition, and the ability to quickly adapt to new annotation guidelines, all of which contribute to delivering reliable, high-accuracy data for AI training workflows.

AI Data Labeling and Salient Image Captioning, Computer Vision Dataset

OtherImageBounding BoxText Generation
Performed data pre-processing for image datasets in computer vision, provided high-precision annotated images and salient captions for AI model training. The task involves recognizing objects and assigning labels to them using Bounding boxes or Coordinate-Based Object Markings. Salient image captions were also generated by focusing on primary objects, actions and scene context meaning for multimodal AI training. Adhered to annotation specifications, quality standards and task directions. Contributed to the development of large-scale datasets for advancing AI image understanding and vision-language models.
