Freelancer Overview

I have experience in structured administrative and customer service work that has strengthened my ability to handle detailed, accuracy-focused tasks—skills that are directly relevant to data labeling and AI training. During my 2 years and 9 months as a receptionist at Ardhi House, I regularly managed high volumes of information, including visitor records, appointment scheduling, calls, and documentation. This role required strong attention to detail, consistency, and the ability to follow procedures accurately, which are essential when working with AI training data and annotation tasks. I also bring strong language and communication skills in English and Kiswahili, along with proficiency in Microsoft Word and Microsoft Excel. My experience in public-facing roles has trained me to interpret information clearly, follow instructions carefully, and maintain high levels of accuracy under pressure. I am highly adaptable, a fast learner, and motivated to contribute to AI projects involving content evaluation, data labeling, and quality assurance while continuously improving my technical and analytical skills.
