I am a multilingual AI data specialist with several years of experience in Swahili-English language annotation, LLM prompt engineering, and AI content evaluation. My expertise lies in developing high-quality datasets for generative AI and conducting human-in-the-loop evaluations to enhance multilingual NLP models. I have a proven track record of collaborating with NLP engineers to improve annotation guidelines and ensure linguistic consistency through rigorous QA processes.
Throughout my career, I have worked on diverse projects, including building intent recognition datasets for chatbots, evaluating AI-generated content for fluency and accuracy, and curating large-scale Swahili corpora for machine learning applications. My technical skills include proficiency in annotation tools such as Labelbox and Prodigy, as well as basic knowledge of Python for data analysis. I am passionate about leveraging my linguistic skills and technical expertise to contribute to innovative AI solutions.
