What I'm looking for

I seek remote or contract roles contributing to AI/ML audio dataset creation, where I can apply linguistic expertise, deliver high-quality annotations, and collaborate on improving model accuracy.

I am a detail-oriented English language specialist with 3+ years in audio annotation, transcription review, and AI model training, delivering precise datasets that improve machine learning performance.

I have native-level English fluency, Kiswahili proficiency, and proven expertise evaluating phonetic accuracy, accents, and natural speech patterns to enhance model comprehension. I consistently meet tight deadlines and maintain rigorous quality standards, including achieving 99%+ grammatical accuracy in transcription reviews.

I thrive in remote, collaborative environments, working closely with project coordinators and QA teams to refine annotation protocols, document linguistic decisions, and flag edge cases that strengthen dataset quality.
