About

Professional summary

I am a freelance AI Model Rater and Linguistic Data Specialist with more than three years of hands-on experience testing, evaluating, and rating AI chatbots and language models.

As a native Amharic speaker from Ethiopia, I bring deep knowledge of cultural context, regional dialects, and authentic language usage. I also work professionally in English and fluently in Oromic.

I conduct structured written and voice-based AI evaluations, assessing model capability, safety, helpfulness, and linguistic quality against assigned prompts and rating criteria.

My localization experience includes English-to-Amharic translation, copy editing, proofreading, terminology management, transcription, annotation, and Linguistic Quality Assurance for marketing, UI/help, life sciences, and medical content.

I am experienced with CAT tools and web-based evaluation platforms, and I can onboard quickly for remote, task-based projects requiring reliable communication and fast turnaround.

I also bring data quality leadership experience from national census programs, where I supervised field data, audited large datasets, trained data collectors, and enforced data integrity standards.
