Labeling Experience

Freelance AI Trainer & Linguistic Expert

Scale AIAudioRLHF

As a Freelance AI Trainer & Linguistic Expert at Scale AI, I contributed to improving model accuracy through data labelling and reinforcement learning with human feedback (RLHF). My responsibilities included linguistic review and evaluation of grammar, fluency, and coherence to enhance LLM understanding. I executed various AI training and text assessment tasks to maintain high dataset quality for language model pipelines. • Trained AI models using text ranking, classification, and instruction following. • Reviewed and annotated STEM, code, and language data for model fine-tuning. • Ensured consistency and quality across large language datasets for LLM development. • Provided expert human feedback for RLHF optimization processes.

Delivery Data Analyst | LLM Trainer

ImageRLHF

As a Delivery Data Analyst and LLM Trainer at Turing, I led the development and deployment of ETL pipelines for optimized LLM fine-tuning using RLHF and SFT. I integrated Vision-LLM models to streamline annotation workflows, performing structured human feedback loops to improve model outputs. My work supported training data creation, evaluation, and quality assurance for advanced language and vision models. • Designed and implemented data pipelines for RLHF-based model tuning. • Automated data annotation to reduce manual effort and accelerate delivery. • Developed evaluation frameworks for quality control in LLM training. • Collaborated with engineers to improve dataset quality and annotation best practices.
