Freelance AI Data Trainer / Prompt Writer
As a freelance AI Data Trainer and Prompt Writer, I crafted and refined diverse prompts across business, finance, and general interest domains to train large language models. I systematically evaluated AI-generated text, using structured rubrics to rate, rank, and provide feedback on factual accuracy, tone, alignment, and helpfulness. My work encompassed RLHF (ranking, reference answer writing), text classification, intent labelling, sentiment and toxicity tagging, and detailed review and correction of model outputs. • Maintained >95% annotation consistency and followed complex guidelines meticulously. • Delivered over 269 high-quality prompts for supervised fine-tuning and evaluation tasks. • Used ChatGPT, Claude, Gemini, and Bard via internal/proprietary tooling on online platforms. • Specialized in business, finance, current affairs, and consumer datasets, with hands-on experience in RLHF and prompt engineering.
