Finance, risk, and operational tools shaped around the people who have to explain the numbers, and act on them.
Designed and shipped an interactive explainer that turns abstract portfolio-risk concepts into manipulable scenarios. The app helps readers see how Sharpe ratio, VaR, CVaR, Sortino ratio, and max drawdown respond to changing assumptions instead of encountering the metrics as static textbook definitions.
Converted a dense risk-education topic into a hands-on learning tool that makes portfolio trade-offs legible in minutes.
Built an interactive risk management playbook written for South Africa's actual operating conditions: twin peaks regulation, load shedding, FATF greylisting, and a crime environment that makes standard BCP templates inadequate. Covers governance (SARB/FSCA, POPIA, FICA/AML), operational risk (load shedding, crime, labour/strike), and strategic/macro risk (geopolitical, reputational, insurance gaps) with a SA-calibrated 5×5 risk matrix and a standards map.
Produced a reference-grade enterprise risk tool used for advisory engagements with SA financial services and corporate clients.
Built a fully interactive demand planning dashboard scoped to South African retail conditions: SA-specific vendors (Tiger Brands, Sasko, Willowton, SC Johnson SA, Nestlé SA), ZAR values, and Durban port lead-time risk baked in. Features a live safety stock calculator using the full lead-time variability formula, Holt-Winters demand forecast with promo-lift modelling, ABC/XYZ SKU classification, escalation alerts, and an open PO pipeline tracker.
Turned a complex operations discipline into a hands-on, explorable tool that planners can use to understand safety stock trade-offs, forecast confidence, and stockout risk in minutes. No spreadsheet required.
An end-to-end loan operations command centre covering deal pipeline, live KPI cards, task queue, and a 3D portfolio globe, built for a commercial lending desk.
Demonstrated operational dashboarding for financial services, combining real-time KPIs, visual pipeline tracking, and 3D data visualisation in a single client-side application.
