What I'm looking for

I’m looking to work on AI quality and trust-and-safety—auditing LLM reasoning/data, detecting hallucinations and logic flaws, and using Python/Excel to deliver zero-defect, asynchronous-ready datasets.

I’m a highly analytical “High-End AI Data Evaluator” specializing in Financial Modeling, Mathematical Reasoning, and AI Data Evaluation. I audit complex Chain-of-Thought (CoT) logic for global AI platforms by identifying linguistic and logical fallacies and strengthening trust, safety, and data quality.

In my freelance work, I conduct rigorous step-by-step verification of mathematical deductions and logic pathways for LLM training, using Python and advanced Excel to process and validate high-volume data batches for zero-defect outputs in asynchronous workflows. I also bring teaching-grade precision from my experience as an Advanced Mathematics Instructor, where I deconstruct problems into clear logical sequences and translate sharp error analysis into high-level AI auditing.
