What I'm looking for

I’m looking for remote, guideline-driven AI data and QA work where multilingual accuracy, confidentiality, and on-time quality matter—helping build safer, high-quality AI systems with clear instructions and measurable standards.

I’m a detail-oriented AI Data Specialist and Quality Assurance Annotator with native-level fluency in Swahili and advanced English proficiency. I support AI training by evaluating and labeling text, audio, image, and video datasets with strong linguistic and cultural accuracy.

In my remote, guideline-driven work, I perform annotation, labeling, counting, and pairwise comparison tasks while running quality assurance checks to catch transcription errors, inconsistencies, and annotation issues. I’m trusted for confidentiality, consistency, and timely delivery that helps teams maintain strong performance metrics.

I’m passionate about contributing to safe, high-quality AI systems and I take pride in meeting SLAs and project deadlines. I’m currently completing a Bachelor of Arts in English and Linguistics to deepen my expertise in language-focused evaluation.
