I have hands-on experience in data labeling and AI training data across multiple task types and platforms, including text, audio, and image-based work. My work has included RLHF, red teaming, prompt-response writing and SFT-style tasks, transcription review and correction, quality evaluation and rating, data collection, and bounding-box image annotation. I have evaluated AI-generated outputs for naturalness, accuracy, factual consistency, instruction adherence, and overall quality, compared alternative responses, written rationales to justify decisions, and contributed to the creation of high-quality example outputs for model improvement. I have also reviewed AI-generated transcriptions for orthography and completeness, corrected them when needed, and fully re-transcribed content when the AI output was too inaccurate to be usable.
What sets me apart is the combination of strong linguistic sensitivity and structured analytical judgment. As a native German speaker with strong English skills, I can work effectively in both languages, including multilingual and code-switching contexts, and I pay close attention to tone, nuance, phrasing, register, and cultural fit. In addition to text-based work, I have experience with audio tasks for LLM-related projects and image annotation for computer vision workflows, which gives me broader exposure than candidates who have only worked in one modality. I am comfortable following detailed guidelines, identifying subtle quality differences, analyzing error patterns, and contributing reliable human judgment across a wide range of AI training workflows.
