Senior AI Training Data Specialist

RemotasksText

I contributed to large language model (LLM) training by rating and annotating complex text dialogues for safety, helpfulness, and factual accuracy. This required following advanced guidelines for LLM alignment and working independently on critical tasks for top-tier AI research organizations. I also participated in quality control, auditing peer annotations and ensuring project guideline compliance. • Advanced LLM prompt evaluation and response rating for alignment and RLHF tasks • Created detailed audit reports to improve annotation processes and team accuracy • Achieved over 99% accuracy across 1,000+ assigned tasks • Utilized web-based tools including Remotasks, Scale AI, and Appen for annotation
