Labeling Experience

AI Training Specialist (Freelance)

TextRLHF

As an AI Training Specialist (Freelance), I performed RLHF (Reinforcement Learning from Human Feedback), prompt evaluation, and high-accuracy data annotation to enhance LLM performance. My work focused on improving language model reasoning, ranking response quality, and ensuring factual, logical, and safety alignment. I contributed across platforms such as Outlier, OneForma, Soul AI, and CrowdGen on a variety of international AI projects. • Applied RLHF to evaluate and rank AI-generated responses. • Conducted detailed prompt testing, scoring, and feedback provision for LLMs. • Ensured factual consistency, logical coherence, and tone adjustment in outputs. • Utilized proprietary and industry annotation tools to maintain high-quality datasets.
