Freelancer Overview

I am an experienced AI data annotator and LLM evaluator with a strong background in reviewing and improving AI-generated transcripts, responses, and structured data. I have worked extensively on projects involving text, audio, and image annotation, ensuring data quality and accuracy for training large language models. My expertise includes fact-checking, prompt refinement, transcription correction, and qualitative output comparison across domains such as health, technology, and business. I am skilled in using tools like OpenAI, Claude, and Google AI Studio, and excel at providing clear, guideline-based feedback to enhance AI system performance. My attention to detail and commitment to maintaining high labeling standards consistently contribute to the development of reliable and effective AI solutions.
