AI Data Trainer / Data Specialist
As an AI Data Trainer, I executed high-quality labeling and annotation tasks on diverse text datasets to support the training of machine learning models. My responsibilities included evaluating AI-generated responses for accuracy, tone, and safety, and providing detailed feedback for continuous model refinement. I leveraged tools such as Labelbox, Scale AI, and Appen to ensure data labeling at scale and with precision. • Conducted large-scale ranking and evaluation of LLM outputs to assess factual accuracy and helpfulness. • Collaborated with data scientists to identify edge cases and refine annotation guidelines. • Applied Reinforcement Learning from Human Feedback (RLHF) to enhance model responsiveness and safety. • Performed high-precision auditing and error analysis for improved dataset quality.
