On freelance platforms, I evaluate and label AI responses against rubrics, then write evidence-based rationales for errors and gaps. I also enter and categorise data according to strict guidelines.

Through academic and personal projects, I write software documentation, including architecture explanations, data flows, and user guides. I built a full-stack fitness tracking and health monitoring app with Spring Boot, React, and MySQL, and wrote its setup guide and API documentation.

In bilingual projects, I translate and transcribe English and Swahili content while preserving meaning, tone, and consistent terminology. I’m studying Software Engineering at the University of Dodoma and have also built a hotel booking web app with Java Servlets/JSP and MySQL.
