Freelancer Overview

I bring extensive experience in AI training data, data annotation, and data labeling, with a strong focus on natural language processing (NLP) and generative AI. My work includes training and evaluating large language models (LLMs) using RLHF, prompt engineering, and preference ranking to ensure high-quality, contextually relevant model outputs. I have hands-on expertise with leading data labeling platforms such as Labelbox, Toloka, and Scale, and have contributed to the creation of structured, reliable datasets that drive model performance and reliability. My background in IT consulting and project management enables me to deliver technically robust and business-aligned solutions, while my collaborative approach ensures clear communication and measurable results. I am passionate about refining AI systems to better serve user intent, and have worked across diverse domains including conversational AI, business automation, and customer support.
