Freelancer Overview

I am an experienced data annotation and AI training data specialist with a background in both qualitative and quantitative research. I have designed and applied structured evaluation rubrics to assess AI model outputs across a range of real-world tasks, including natural language processing, information synthesis, and user query evaluation. My work involves detailed annotation, accuracy and relevance assessment, OCR validation, and the identification of systematic failure patterns to support model fine-tuning. I am adept at maintaining high inter-rater reliability, adapting quickly to evolving guidelines, and delivering consistent, high-quality results under tight deadlines. My technical toolkit includes Excel, SPSS, and foundational analytics tools, and I have contributed to projects in sectors such as healthcare, policy, and digital applications. I am committed to ensuring data quality and integrity in every stage of the AI training process.
