Freelancer Overview

I have experience in AI training data evaluation and quality assurance within contract-based environments. My work involved assessing AI-generated outputs using structured rubrics to evaluate accuracy, coherence, and alignment with reference responses. I performed ranking and error detection tasks, applied guideline-based evaluation criteria, and contributed to structured quality assurance workflows designed to improve model response reliability. I also worked on multilingual data validation tasks, including transcription verification for Korean audio, where I reviewed and corrected AI-generated text for alignment and accuracy. In addition, I contributed to structured evaluation task development involving behavioral and clinical scenario frameworks used for model testing. Across these roles, I developed strong skills in rubric-based assessment, consistency checking, ambiguity detection, and high-volume structured annotation workflows requiring precision and strict adherence to guidelines.
