Freelancer Overview

I have direct experience with large-scale data annotation, having organized and annotated hundreds of thousands of documents as part of an EdTech startup, giving me a practical understanding of the pipeline, consistency challenges, and quality control processes that make training data actually useful at scale. I have also built production RAG systems and trained models for client companies, which means I approach data labeling not just as a tagging exercise but with a clear understanding of how annotation decisions downstream affect model behavior and performance.
