WHO I AM

About Me

I'm a Data Scientist and Business Analytics professional with 2+ years delivering predictive models, risk analytics, and BI solutions across banking, financial services, and large-scale manufacturing. I specialize in Python, SQL, SAS, and Power BI—building end-to-end analytics pipelines, developing machine learning systems, and designing dashboards that solve real business problems.

My recent work includes credit risk modeling on 1M+ loan applications achieving 87% precision, Azure-based production analytics delivering R38M in savings, customer segmentation enabling targeted marketing strategies, and automated financial reporting reducing manual work by 50%. I've built solutions processing 500,000+ customer records, analyzing 250,000+ production events monthly, and enabling data-driven decisions for executives and operations teams.

My Postgraduate Diploma in Data Science (Cum Laude) and dual engineering background give me a unique combination: the statistical rigor of a data scientist, the systems thinking of an engineer, and the business acumen to translate analytics into measurable ROI. I build ML and analytics solutions that are robust, scalable, and business-focused—with a clear pathway toward senior Data Scientist, ML Engineer, and AI/ML Architect roles in financial services.
