AI Trainer & Data Annotator (Freelance)
As an AI Trainer & Data Annotator (Freelance), I executed RLHF, preference labeling, and SFT tasks for text-based datasets supporting LLM development and evaluation. My work included rating, ranking, and annotating AI model outputs, ensuring high-quality annotated data for training. I maintained annotation consistency while performing tasks at scale and meeting platform-defined accuracy requirements. • Rated and ranked AI model responses using RLHF workflows• Performed preference labeling and pairwise comparisons on AI-generated text in coding, reasoning, and creative writing domains• Annotated datasets for supervised fine-tuning, including instruction-following and summarization• Conducted red teaming exercises to identify, flag, and describe harmful or biased outputs
