KenyaWhat I'm looking for
I’m a Results-driven Software Engineering student and AI Data Specialist focused on language data quality, annotation reliability, and AI training workflows. I bring native Kiswahili fluency (Kenya) and strong English proficiency to bilingual judgement tasks.
I’ve completed data annotation and content review work as a freelance, self-directed AI Data Specialist—evaluating AI-generated Swahili text for fluency, factual accuracy, cultural appropriateness, and safety compliance. I maintain annotation consistency across extended sessions and document quality issues, edge cases, and structured feedback to support iterative model improvement.
In my Software Engineering Intern / Project Developer experience at Zetech University, I designed and deployed PesaPal, a Flutter + Supabase budgeting app with real-time analytics and user-testing feedback loops. I also build reliable data visualisation features, collaborate in Agile environments, and deliver group solutions consistently ahead of deadlines.
