What I'm looking for

I’m looking for remote, quality-driven work where I can annotate, transcribe, and evaluate multilingual AI outputs—staying accurate, efficient, and aligned to detailed guidelines that improve dataset quality.

I’m a Bilingual AI Data Annotator and Transcription Specialist with 3+ years of experience training and improving AI language models. I’m fluent in Kiswahili and English, and I focus on high-quality transcription, multilingual annotation, and evaluating machine-generated outputs.

In remote, fast-paced environments, I review and improve AI-generated text and transcription outputs against strict quality standards, correcting linguistic and contextual errors while maintaining high accuracy and productivity. I also follow detailed guidelines closely—identifying speaker segments, accents, and background noise—so datasets stay consistent, reliable, and ready for downstream AI use. My professional ethos is simple: attention to detail, guideline adherence, and measurable quality improvements every day.
