Freelancer Overview

I am a detail-oriented remote professional with hands-on experience in data annotation, labeling, and content review for AI training projects. My background includes labeling and reviewing both text and image data, recording high-quality video data for computer vision tasks, and ensuring strict compliance with project guidelines. I am skilled at maintaining high accuracy and consistency, performing quality checks, and handling sensitive information with confidentiality. I am comfortable working independently, meeting deadlines, and adapting quickly to new workflows and evolving annotation guidelines. I am proficient with Google Workspace, Microsoft Office, PDF editing tools, and familiar with TELUS and Lionbridge-style annotation platforms. My strong attention to detail, clear written communication, and flexible availability make me well-suited for demanding AI data labeling and moderation roles.

I worked on AI training projects where I reviewed, labeled, and annotated data to help improve machine learning models. I particularly enjoyed contributing to their POV / first-person video data collection initiative. This was a short-term contract, and I’m still awaiting new projects with them.

I work on data annotation projects involving the labeling and review of videos. Sometimes we have to cut clips or merge them if they’re too short or don’t make sense, to make sure the final video flows well, is clear, and can be easly understood.
