David Masaku

I’m a Data Annotation Specialist and Linguist with over seven years of experience creating and validating annotated and labeled datasets for AI model training. I deliver accurate, consistent, and high-quality training datasets by following strict annotation guidelines across evolving project requirements.

I’ve worked as a project coordinator, linguist, transcriptionist, and Argos Multilingual proofreader—conducting QA reviews to identify errors and improve labeling precision. I collaborate with teams to resolve data issues quickly and maintain consistency from task briefs through final outputs.

Beyond annotation, I coordinate workflows, receive client briefs, assign tasks, and train and onboard transcribers on quality standards and guideline compliance. I’m dependable, detail-oriented, and motivated to keep improving quality—because clear, reliable data is what makes AI work.
