Freelancer Overview

Senior AI Training & Evaluation Specialist with 3+ years of experience in fine-tuning next-generation LLMs through RLHF, reasoning evaluation, and multi-turn prompt engineering. I have successfully completed 5,000+ model iterations, focusing on hallucination elimination, logical rigour, and HHH compliance (Helpfulness, Honesty, Harmlessness). My expertise includes working with complex reasoning models like the o1-series and GPT-5, as well as multimodal data types such as Text-to-Video and Text-to-Image. Leveraging a technical background in Information Systems (M.Sc., KNEU), I excel at structured data labeling using JSONL and Markdown, ensuring high-quality datasets for supervised fine-tuning. Beyond annotation, I am proficient in technical research and fact-checking for STEM and coding domains, always maintaining a focus on precision and human-aligned model responses.
