Freelancer Overview

I have strong experience in Reinforcement Learning with Human Feedback (RLHF) and Supervised Fine-Tuning (SFT) projects in German. I’ve also contributed to math, science, and STEM evaluation projects, where precision and subject-matter knowledge are essential for producing high-quality datasets. My key strengths include linguistic accuracy, attention to detail, and the ability to apply complex guidelines while handling edge cases. Combining language expertise with technical reasoning, I ensure the correctness and authenticity of outputs produced by LLMs.
