What I'm looking for

I'm seeking a Data Annotation or AI Training Data role where I can apply my LLM output evaluation, rubric-based quality assessment, and annotation experience to improve model alignment and data quality.

At Ethara AI, I evaluated and annotated LLM-generated images and videos across 500+ prompts daily, assessing prompt adherence, visual quality, and AI-generated artifacts against client rubrics.

I rated and ranked model outputs with detailed written justifications, maintaining a 90%+ quality and consistency score across Image Compare, Rubric Rating, and Justification Writing tasks. Through the Multimango AI Output Evaluation project, I produced structured annotations used to improve model training data.

Alongside AI evaluation, I’ve delivered 100+ marketing creatives for 30+ freelance clients and built brand identity packages, combining visual judgment with attention to detail.
