What I'm looking for

I’m seeking a remote Kiswahili AI Model Rater role where I can apply my linguistic judgment and cultural fluency to improve model quality and safety.

As a freelance audio transcriber and Spanish translator, I converted multi-speaker audio and video into accurate, time-stamped scripts, maintaining a 99% accuracy rate.

I translated and localized technical documents, audio, and conversational data from Spanish into English and Kiswahili, preserving cultural and grammatical context. I also proofread transcripts and flagged ambiguous or culturally inaccurate phrasing.

I formatted and labeled linguistic data to support machine learning and automated speech recognition systems. I’m a native Kiswahili speaker with experience in AI content evaluation, prompt and response rating, and remote work.
