Labeling Experience

Generalist AI Trainer

OtherTextPrompt Response Writing SFT

As a Generalist AI Trainer at RemoExperts, I wrote, edited, and refined high-quality prompts and model responses on a wide range of topics for LLM training. I critically evaluated AI-generated text for accuracy, tone, style, and safety, providing detailed feedback for model improvement. I conducted adversarial red teaming, hallucination detection, and fact-checking to identify and mitigate model flaws. • Delivered multi-domain training data including technical topics (computer science, math, etc.) • Applied complex project instructions across concurrent annotation tasks • Maintained elite-level quality and consistent guideline compliance • Utilized annotation platforms and custom tools for data submission
