Freelancer Overview

I have extensive experience in AI training data evaluation and labeling for some of the world’s leading technology and AI research organizations. My work spans LLM evaluation, prompt engineering, red-teaming, RLHF, instruction-following assessments, and multilingual QA across English, German, and Swiss German. I have contributed to high-impact projects shaping next-generation AI systems, collaborating on text generation, summarization, translation/localization, and fine-tuning tasks with strict quality and consistency standards. Beyond evaluation, I specialize in guideline interpretation, quality control frameworks, and prompt+response SFT writing, enabling AI models to meet linguistic precision, cultural nuance, and ethical alignment requirements in fast-paced, remote-first environments. This combination of technical accuracy, language expertise, and real-world project experience allows me to deliver top-tier training data for state-of-the-art AI systems.
