What I'm looking for

I’m looking for work where I can apply linguistics and multilingual expertise to improve AI training datasets and evaluations, with clear guidelines, fast feedback loops, and an emphasis on accuracy and consistent quality.

I’m a Swahili language specialist with a strong foundation in linguistics, multilingual communication, and AI language training. I combine linguistic and contextual analysis with careful dataset work to help AI systems interpret intent correctly and produce clear, accurate outputs.

In my current work as an AI Data Annotator, I annotate and evaluate text, speech, and image datasets for AI model training while maintaining strict accuracy and consistency. I review outputs, provide actionable feedback, and apply detailed linguistic reasoning across diverse datasets to improve performance.

I’ve also supported AI through roles including AI Data Annotation Specialist and AI Rater/Evaluator, where I ensured high-quality labeling and identified inconsistencies, biases, and factual errors. Alongside annotation expertise, I bring skills in AI language training, workflow automation, and cloud-based data systems (AWS) to strengthen end-to-end language technology workflows.
