Freelancer Overview

I am a Swahili linguist and AI language specialist with extensive experience in data annotation, linguistic analysis, and AI training data preparation. My background includes annotating and evaluating Swahili text and audio for grammar, syntax, morphology, phonetics, and semantics, with a strong focus on NLP and speech-based projects. I have worked on a variety of domains, including e-commerce, telecom, and medical data, ensuring high-quality datasets for machine learning systems. I am skilled in identifying and documenting model errors, curating glossaries, and providing clear rationales for annotation decisions. I am comfortable working with detailed guidelines, meeting productivity targets, and using advanced tools such as XTM and Trados for CAT, as well as transcription and quality evaluation platforms. My ability to work independently and my attention to detail help me consistently deliver accurate and culturally appropriate language data for AI applications.
