What I'm looking for

I’m suited to data annotation and AI training work, drawing on my experience testing systems, documenting requirements, and evaluating system output.

At Centric Limited, I contributed to DDSign, a live electronic document signing platform, and designed and executed 115 user acceptance test cases across its web and mobile modules. I also authored product documentation, including a product report, user manual, and defect report.

For my final-year project, I’m building a decision support system that predicts late-payment risk for Kenyan SMEs and explains its predictions with SHAP. My work spans data engineering, machine learning, and web development, and I also deliver web development, website management, and data analysis for freelance clients.
