What I'm looking for

I'm seeking entry-level opportunities in Data Analysis or Data Science.

At RWS, I performed Named Entity Recognition tagging and labelled image attributes and UI elements for machine learning datasets. I also evaluated AI-generated outputs and provided structured feedback to support model performance and output quality.

I hold a BSc in Mathematics and Computer Science from the University of Limpopo. At Penreach, I assisted students with mathematics and science coursework and supported teachers with lesson preparation.
