James Spiller
@jamesspiller
AI training specialist improving LLMs through HITL workflows, RLHF/SFT, evaluation, and data-quality assurance.
What I'm looking for
I’m an AI Training Specialist and digital marketing professional focused on data annotation, LLM evaluation, RLHF, and supervised fine-tuning. I help align model outputs with human expectations through instruction following and prompt + response writing.
Since Jan 2023, I’ve worked as a freelance AI trainer and data annotation contractor across Appen, Clickworker, Data Annotation Tech, OneForma, RWS, and Scale AI. I perform evaluation/rating, preference ranking tasks, and RLHF workflows, and I audit datasets for bias, policy compliance, hallucinations, and edge cases.
I maintain strong annotation accuracy and inter-rater reliability using Labelbox, Hive, Prodigy, Excel, JSON, and Python to manage and review datasets. Outside of AI, I’ve built organic content strategies that generated hundreds of millions of views, combining SEO optimization and performance analytics with careful content review for accuracy, clarity, and compliance.
