I am an Analytical AI Training Specialist with hands-on experience in data annotation, reinforcement learning from human feedback (RLHF), and large language model (LLM) evaluation. My background includes evaluating and ranking AI-generated responses for helpfulness, accuracy, and safety, as well as conducting in-depth fact-checking and research to ensure high-quality training data. I have expertise in identifying subtle model hallucinations, crafting diverse prompts to test model capabilities, and providing precise rationales to improve model performance. My skills span supervised fine-tuning (SFT), multi-turn conversation annotation, and image-to-text tasks, and I am well-versed in AI safety guidelines and bias detection. I am passionate about maintaining data integrity and contributing to the development of reliable, ethical AI systems.
