Selected work.
Shipped systems, technical prototypes, and concept pieces — from internal platforms to data & ML.
IT Financial Dashboard
Kagiso Trust · Internal
Full-stack financial platform centralising IT budgets, expenditure, vendors, and invoices. KPI cards, spend breakdowns, multi-year trends, Excel/PDF export, and a conversational AI Finance Assistant.
Stakeholder & Partnership System
PMO · Kagiso Trust
Centralised platform managing 700+ stakeholder and research records across Trusts, Corporates, Foreign Missions, and Education entities — with bulk uploads, exports, and dashboard views.
TVWS ConnectView
TV White Space Programme · Limpopo
Monitoring platform for school connectivity. ICT Champions log incidents and outages; administrators get dashboards for uptime, signal strength, and resolution tracking.
CSSP Programme Management System
Prototype · Kagiso Trust
Working prototype built from a BRD to demonstrate workflows ahead of an RFP. Used to validate requirements and align stakeholders prior to full-scale development.
Dependency Map — Pandemic Response
Concept · Digital Ecosystem
Interactive dependency map visualising how healthcare providers, IT teams, policymakers, and infrastructure layers connect in a digital pandemic-response ecosystem.
BC/DR Plan — Digital Education
Concept · Resilience
Conceptual business-continuity and disaster-recovery view for a digital education stack, focused on resilience in low-connectivity environments.
Architects of Inclusive Digital Education
Story-driven concept
Story-driven digital concept mapping an inclusive digital-education ecosystem, from infrastructure and content through to learners and communities.
Journey Through the OSI Layers
Interactive explainer
Interactive educational experience that uses narrative and visuals to explain the OSI model and how data moves across network layers.
Football Match Outcome Prediction
Supervised Learning · Python
Multi-class classification predicting match outcomes (home win, away win, draw) across the Premier League, La Liga, Bundesliga, and MLS. 30+ features and feature engineering, comparing logistic regression, decision trees, random forests, and ensembles on accuracy, precision, recall, and F1.
EV Driving-Range Regression
Predictive Analytics · Python
Regression modelling on 261k+ electric vehicles with 30+ features to predict driving range. Data-quality checks, multicollinearity and normality testing, and Linear Regression vs Decision Tree vs Random Forest compared on R², RMSE, and MAE — with residual analysis and market segmentation.
Investment & Retirement Analysis
Financial Data Analysis · Python
Evaluates crypto, international ETFs, SA indexes, and gold over 45 years of history to build an optimal R100k strategy. Combines descriptive statistics, linear-regression forecasting, and volatility with tax- and inflation-adjusted retirement projections across life scenarios.
Monte Carlo Retirement Simulation
Probabilistic Modelling · Excel
Monte Carlo simulation over a 43-year horizon, running thousands of randomised scenarios for income, returns, inflation, and expenses to produce probability distributions of retirement outcomes and quantify risk (e.g. an 85% chance of accumulating R5M+).
Lifetime Financial Simulation Model
Financial Modelling · Excel
Excel model simulating personal financial health across a 63-year lifespan (age 22–85) — salary growth, rent-to-ownership and vehicle transitions, and inflation-adjusted expenses — to project cumulative savings and net worth through retirement.
Time-Series Forecasting — Daily Steps
Predictive Analysis · Python
Forecasts daily step patterns across 15 months of fitness data. Full EDA, seasonal decomposition, and stationarity testing (ADF), with ARIMA and exponential-smoothing models compared on RMSE, MAE, and R² and validated against held-out data.
ML Classification & Evaluation
Python · scikit-learn
Practical machine-learning project implementing and comparing multiple classification models, with evaluation, using Python and scikit-learn.
BI Dashboard Demo — Kagiso Trust
Front-end demo
Front-end demo for a business-intelligence platform, showing how programme metrics and trends could surface through interactive dashboards.
