Freelancer Overview

Language Tutor in Contract Review, Compliance, and Research. Brings 13+ years of professional experience across complex professional workflows, research, and quality-focused execution.

Labeling Experience

Swahili Annotation

The project focused on Swahili data annotation. My role involved listening to audio recordings and refining AI-generated transcriptions to ensure they accurately reflected what was spoken. I was also responsible for segmenting the audio and labeling speakers to make them easily identifiable. The project ran for three months and included a variety of audio files ranging from 10 minutes to 1 hour in length, each with different lengths. For quality assurance, the work underwent a two-stage review process. After the first inspection, any identified errors were returned for correction before resubmission. The corrected tasks were then reviewed again twice for final approval and successful completion.
