01 / About Me
THE PERSON
BEHIND THE MODELS.
I'm a data scientist and economist who builds models and understands why every decision behind them matters, from the validation method to the cost of a wrong prediction.
My work spans Predictive Modelling, Forecasting, fraud detection, credit risk Analysis, and econometrics, and I take each model past the notebook into a live, deployed system.
I'm also a researcher with published papers and international research grant. I bring a researcher's statistical rigour and an engineer's follow-through.

WHAT CLIENTS SAY.
Kind words from people I've had the pleasure of working with.
Gideon turned a vague brief into a fraud detection solution that paid for itself within weeks. Clear updates at every step, and the final report was the most professional analytics work I have received from any freelancer.

The first project went so well that I came straight back to him with a bigger one, and he still over-delivered. Communication was flawless, deadlines were met early, and the results were beyond what I paid for.
