Freelancer Overview

I have hands-on experience contributing to AI training datasets through my work as a data annotator and labeler with Clickworker and as a Home Activities Video Contributor with Micro1. At Clickworker, I worked on data annotation tasks that involved labeling and categorizing datasets according to detailed project guidelines to support machine learning models. This required strong attention to detail, consistency, and the ability to quickly understand labeling instructions while maintaining high-quality outputs across large volumes of data. At Micro1, I contributed to AI training by recording and submitting home activity videos designed to help improve real-world AI understanding of everyday tasks. I ensured that videos followed specific project requirements and accurately represented the requested activities. Across both roles, I developed skills in following structured guidelines, maintaining data quality, and delivering work reliably within deadlines. My experience working on distributed AI training projects has strengthened my ability to produce accurate, well-structured training data that supports the development of reliable AI systems.
