About

I got into software engineering because I wanted to build things that actually mattered — not just demos, but systems people use. I studied at Nelson Mandela University, spent time supporting student wellness (which taught me more about communication than any lecture did), and then went full-send on software — freelancing, capstone projects, contract work. Now I'm at the Academy of Accelerated Technology Education in Johannesburg, sharpening my craft. I like clean architecture, honest code, and shipping things that work.

Credit Card Fraud Detection

End-to-end fraud detection on 284,807 real transactions (0.17% fraud rate). Tackled class imbalance with SMOTE, then benchmarked three models. XGBoost delivered the best results — AUC 0.982, F1 0.863, precision 0.944 — while SMOTE-enhanced logistic regression brought recall up from 0.579 to 0.794. Findings surfaced through a Power BI monitoring dashboard.

DataQuest Recommender

Built for the Dataquest 2025 Recommender Systems Challenge. Progressed from global popularity models through UBCF and IBCF to a final 4-signal weighted hybrid (UBCF + IBCF + regional + seasonal patterns). IBCF achieved the best raw precision (0.022) and recall (0.109) at k=5, but the full hybrid was chosen for real-world deployment suitability — it adapts to context rather than just optimising a metric.
