What I'm looking for

I’m looking for a role where I can deliver high-precision AI training through RLHF and LLM evaluation—auditing for safety and factuality, improving dataset quality, and collaborating to hit clear QA/KPI targets.

I’m an analytical and detail-oriented AI Training Specialist with expertise in RLHF (Reinforcement Learning from Human Feedback) and LLM evaluation. I audit AI-generated content for faculty, logical reasoning, and safety—identifying model hallucinations and producing high-quality golden responses to improve learning accuracy.

Across high-volume freelance data annotation, I’ve maintained a 98% accuracy rating while verifying the factuality of AI responses to ensure zero misinformation. I also rank and rate LLM responses using Helpfulness, Honesty, and Harmlessness (HHH), and coordinate large-scale datasets with strict data integrity and privacy compliance.
