As a Freelance AI Data Annotator & Language Specialist, I annotated and categorized text datasets for NLP model training and evaluated AI-generated responses for accuracy, safety, helpfulness, and tone.
I transcribed Swahili and English audio, labeled voices, and performed phonetic alignment for speech recognition models. I also labeled and segmented image and video data using bounding boxes, polygon masks, and semantic tagging.
I processed and verified structured datasets, reviewed and ranked model outputs against rubrics, and conducted multilingual quality checks in Swahili and English. I bring experience with text, audio, image, video, and tabular data annotation.
