Labeling Experience

AI Data Labeler / LLM Evaluator (Contract)

Text

As an AI Data Labeler and LLM Evaluator at Outlier.ai, I evaluated large language model outputs for mathematical reasoning and coding tasks. My work included validating step‑by‑step solutions, annotating logical errors, and generating or reviewing prompts and answers according to strict rubrics. I also completed coding evaluation tasks and performed structured time-tracked evaluations across multiple projects. • Validated mathematical reasoning and annotated logical errors (Hickory Project). • Generated, reviewed, and graded math prompts and solutions (Mechan Glen Project). • Performed Python coding tasks in Docker environments (SkillMaster Project). • Conducted structured AI evaluation tasks with detailed tracking (Aether Project).

SWE Evaluator

Mercor

As an SWE Evaluator at Mercor.com, I participated in benchmarking software engineering tasks for AI model training datasets. My responsibilities included solving algorithmic problems and documenting the reasoning and correctness behind solutions for use in AI fine-tuning. I ensured all solutions adhered to rubric standards for clarity and reproducibility. • Solved algorithmic/programming tasks for dataset creation. • Documented detailed reasoning and correctness checks. • Supported rubric-based grading for solution review. • Helped create data for LLM fine-tuning and evaluation tasks.
