What I'm looking for

I’m looking for a role focused on AI model evaluation and training data quality, with clear guidelines, thoughtful feedback expectations, and room to improve model accuracy through structured, independent work.

I’m a detail-oriented AI generalist with hands-on experience evaluating AI model outputs, reviewing training data, and identifying inconsistencies and failure modes. In my work, I follow clear task guidelines precisely, work independently with minimal supervision, and document observations transparently to support better training and fine-tuning decisions.

Across roles, I’ve contributed high-quality training data, supported RLHF-style workflows, and produced structured reports that communicate reasoning and uncertainties clearly. I also bring technical familiarity—like Python, data pipelines, JSON/CSV outputs, prompt engineering, and LLM interaction—so I can engage confidently with AI systems across varied task types.
