Mary N

I’m an AI Data Analyst and AI Training & Evaluation Specialist with experience supporting large language models and machine learning systems through high quality data annotation, model evaluation, factual verification, and dataset quality assurance.

I analyze structured and unstructured datasets, validate model outputs, and strengthen data quality pipelines. I focus on prompt analysis, reasoning assessment, response ranking, and hallucination detection to improve the reliability of LLM outputs.

Through remote, global collaborations as a freelance AI Training & Evaluation Specialist (Turing) and AI Data Annotator (RWS Moravia), I deliver high accuracy datasets for training and evaluation. Earlier, I worked as a Data Analyst at Momentum (2021–2024) and completed a Data Entry Specialist trainee role at KNBS, building strong foundations in data cleaning, validation, and reporting.
