What I'm looking for

I’m looking for remote work improving multilingual AI through translation evaluation, LQA, and structured human feedback, with clear guidelines and consistent turnaround expectations for long-term collaboration.

I’m a detail-oriented AI Translation Evaluator with over 4 years of experience supporting AI and machine learning projects through translation evaluation, linguistic quality assurance, multilingual annotation, and AI response assessment. I’m a native Oromo and English speaker with extensive experience working on remote AI training projects involving machine translation, multilingual conversations, and natural language processing datasets.

I evaluate AI-generated translations and LLM outputs for accuracy, fluency, grammar, tone, style, semantic equivalence, and cultural appropriateness, consistently maintaining guideline compliance. I also support translation post-editing, localization review, terminology consistency, and dataset validation, delivering structured human feedback that helps improve multilingual AI systems.
