I build credit-risk models and data products that improve customer prioritisation and portfolio decisions.
South AfricaWhat I'm looking for
At Drive24, I extract, clean, join and analyse relational data to support credit-risk, customer-approval, lead-prioritisation and portfolio-performance decisions.
I've developed XGBoost, CatBoost and logistic-regression models, explainable risk scorecards, and rule-based ranking frameworks using customer outcomes, financial variables and credit-related data. I evaluate model performance with ROC-AUC, KS statistics, confusion matrices and out-of-sample validation.
I'm completing a Bachelor of Computing in Business Intelligence while building dashboards and stakeholder-facing reporting in Power BI, Excel and Amazon QuickSight. I'm interested in applying experimentation, causal inference, personalisation and responsible AI to improve business outcomes.
