As an LLM Trainer and AI Data Specialist at Alignerr, I performed structured evaluations of large language model outputs according to established project rubrics. I systematically reviewed, compared, and rated alternative model responses for quality, clarity, and instruction adherence. My work demanded precision, analytical reasoning, and adaptive review techniques in response to dynamic guidelines. • Evaluated LLM text outputs for correctness, clarity, and instruction-following • Flagged errors such as hallucinations, weak reasoning, or unsupported claims • Maintained consistency in annotation across frequently updated standards • Supported continuous improvement of model evaluation workflows
