Freelancer Overview

I am an AI Data Annotator with hands-on experience in training and improving large language models through data annotation, linguistic evaluation, and quality assurance. I have worked on Hindi (hi_IN) and English (en_IN) datasets, reviewing, labeling, and correcting text for grammar, intent, tone, cultural relevance, and factual accuracy. My work involves evaluating AI-generated responses, refining prompts, and ensuring compliance with detailed project guidelines. I have contributed to AI training projects focused on language understanding, response quality, localization, and instruction adherence. Through systematic annotation and evaluation, I have helped improve model fluency, coherence, naturalness, and overall user experience for Indian audiences. My attention to detail, strong language skills, and commitment to quality enable me to deliver accurate and reliable annotations that support the development of high-performing AI systems.
