Freelancer Overview

I am an experienced data annotator and quality analyst with a strong background in supporting AI training data pipelines across text, audio, and visual domains. My hands-on experience includes annotating over 500 visual contents, labeling objects, movements, scenes, and time-based events for computer vision projects, and evaluating search engine results to improve algorithms and recommendation systems. I excel at following complex guidelines, applying consistent judgment, and providing constructive feedback to ensure high-quality data. With a solid foundation in Computer Science and a Microsoft Certified: Azure AI Fundamentals certification, I am proficient with tools such as CVAT, Adobe Creative Suite, Microsoft Office, and Google Workspace. My attention to detail, contextual analysis, and fluency in English enable me to deliver accurate labeling, verification, and documentation for large-scale AI projects.
