What I'm looking for

I seek a role improving LLM quality through prompt engineering, dataset curation, and automated evaluation in a collaborative, ethics-focused team.

I am an AI Data Specialist focused on improving English AI-generated content through prompt engineering, model fine-tuning, and rigorous evaluation practices.

I design testing frameworks and build linguistically diverse training datasets to enhance grammar, style coherence, and factual accuracy for language models.

I automate evaluation pipelines using Python and metrics such as BLEU, ROUGE, and BERTScore, and implement RLHF loops to align models with style guidelines and brand voice.

I collaborate with ML engineers on fine-tuning, lead large-scale annotation projects, and build tooling like dashboards and bias-detection pipelines to reduce errors and accelerate model improvements.
