Prompt Response Writing SFT

Freelancer Overview

I have experience contributing to AI training and data annotation projects through structured evaluation and quality review of large language model (LLM) outputs. While working on Project Aether with Outlier, I analyzed and ranked AI-generated responses based on accuracy, coherence, factual reliability, and alignment with detailed project guidelines. My role required careful attention to nuance, consistency, and structured reasoning to ensure high-quality training data. Through this work, I developed strong analytical skills, precision in following annotation frameworks, and a clear understanding of how AI systems are evaluated and refined. I am comfortable working within performance benchmarks, maintaining quality standards, and contributing to iterative model improvement processes.
