I am a BCom Information Systems graduate who earned my degree with distinction and a strong focus on data-driven decision-making. My academic work combined machine learning and social media mining to surface actionable insights for digital risk and consumer trust.

I built and evaluated supervised models—including decision trees and logistic regression—to classify fraudulent mobile banking transactions and phishing incidents, and I conducted social media sentiment analysis revealing spikes in scam reports and communication gaps.

I optimised end-to-end data preparation pipelines in R Studio, performed anomaly detection, and produced data-driven SWOT and BI reporting for Capitec’s digital infrastructure, recommending enhancements to client security awareness and responsiveness.

Outside of academics, I balanced part-time work and national-level athletics, demonstrating resilience, discipline, and teamwork. I am ready to contribute as a junior data analyst or data analyst intern, turning complex datasets into clear, strategic narratives.
