What I'm looking for

I’m looking for remote, project-based AI data operations work where I can deliver accurate, guidelines-driven annotations, participate in calibration, and maintain strong quality and confidentiality—especially on multilingual, multimodal training datasets.

I’m a detail-oriented and quality-driven Data Annotation Specialist with 5+ years of experience supporting AI and machine learning initiatives through accurate data labeling, content evaluation, and quality assurance.

I’ve annotated, labeled, and categorized high-volume multimodal datasets (text, image, audio, video, and multimodal) while strictly following complex project guidelines, meeting productivity targets, and delivering reliable structured outputs.

I actively participate in calibration sessions, apply feedback to improve annotation accuracy, and document observations—communicating technical challenges to project leads to help drive process improvements.

Fluent in English and Kiswahili, with German proficiency for reading and annotation, I bring strong analytical skills and reading comprehension to multilingual AI training projects, alongside a disciplined focus on data privacy, confidentiality, and remote workspace security.
