Freelancer Overview

I am a detail-oriented professional with a strong background in structured digital work and technical systems. While transitioning into AI data annotation and training projects, I bring proven experience in following detailed guidelines, maintaining consistency, and executing repetitive tasks with high accuracy. My background in web design and technical electrical work has developed my precision, focus, and ability to interpret written instructions carefully — all critical skills for data labeling and AI evaluation tasks. I am particularly strong in text classification, sentiment analysis, AI response evaluation, and content categorization. I work independently in remote environments, maintain sustained productivity (6+ hours daily), and prioritize quality control over speed. My disciplined workflow, reliability, and attention to detail allow me to contribute effectively to AI training, data annotation, and content moderation projects.
