I conducted instruction-following evaluation and pairwise preference ranking of AI-generated outputs, delivering structured human feedback to support RLHF model fine-tuning and alignment workflows. I validated and QA-reviewed annotated data against quality benchmarks and contributed to multiple concurrent projects.• Labeled and classified complex text datasets for natural language processing tasks • Performed preference ranking, safety flagging, and conversational flow labeling • Adapted rapidly to evolving annotation guidelines and rubric changes • Provided QA and feedback on annotated batches to maintain dataset integrity
