Labeling Experience

Freelance Linguist and Translator

Text

In my role as a Freelance Linguist and Translator, I reviewed, translated, and localized technical, educational, and digital content between English and Swahili for AI training datasets. I provided linguistic QA for AI-generated text, corrected grammar and semantics, and contributed structured explanations for complex cases. My work supported improved model reliability, realism, and contextual understanding of language models. • Performed translation and localization tasks to expand multilingual AI dataset quality. • Validated and corrected textual data for grammatical and semantic accuracy. • Developed contextual and cultural annotations to enhance AI language training. • Provided feedback on language patterns and dataset adaptation for multilingual AI systems.

RemotasksImageBounding Box

As a freelance Data Annotator and AI Model Evaluator, I annotated images and video frames using bounding boxes, polygons, and segmentation tools to train computer vision models. I also labeled 3D objects and LiDAR point cloud datasets to ensure accurate spatial representation for AI training. Additionally, I conducted regular AI response evaluations and maintained dataset quality through structured documentation and QA checks. • Applied bounding boxes, polygons, and segmentation masks to images and video using Remotasks, Scale AI, and Outlier platforms. • Labeled 3D objects and LiDAR point cloud data for autonomous technologies and perception systems. • Evaluated AI model responses for accuracy, instruction adherence, and contextual relevance. • Collaborated on remote annotation and documentation for consistent high-quality dataset preparation.
