Freelancer Overview

I have hands-on experience in data annotation and AI training data projects, having delivered high-quality annotations and evaluations for international clients such as Appen, Data Annotation.Tech, and Telus International. My work includes assessing the relevance and quality of online advertisements, analyzing search results, and ensuring data accuracy for improved AI model performance. I am skilled in CRM systems, ticketing support, and digital operations, and I bring strong attention to detail, linguistic accuracy, and a commitment to data integrity. My background in sales, customer support, and project coordination further enhances my ability to manage and execute data labeling tasks efficiently across various domains.

Labeling Experience

Video Labeling Specialist | Atlas Capture

Internal Proprietary ToolingVideoBounding BoxObject Detection

As a Video Labeling Specialist, I annotated and labeled objects, actions, and events in video footage frame-by-frame. I applied bounding boxes, polygons, and segmentation techniques to track objects for computer vision model training. I reviewed and quality-checked annotated video datasets for compliance and error correction. • Ensured precise temporal and spatial accuracy throughout dynamic video scenes • Applied advanced annotation techniques like semantic segmentation • Maintained high data integrity through continuous quality checks • Worked on computer vision datasets for model training
