Ronny O.

Over three years in data annotation and AI training, I've worked across healthcare, public safety, and logistics — handling everything from LLM fine-tuning to medical data accuracy reviews. At ADEC, I maintained a 99% accuracy record; at CloudFactory, I fine-tuned LLMs for real-time public safety decisions — a role I've since returned to as a Data Analyst. I bring a strong eye for detail, a track record of measurable results, and a clear understanding of what good AI output looks like — and what it costs when it isn't.
