Portfolio

Mental health service website development

Oxford Mental Health Network

Fighting match app

React Native mobile application development

PONRAM App

A library for n-dimensional Monte Carlo localization.
Monte Carlo Localization (MCL) is useful in scenarios where uncertainty arises in a system over time (as a result of error; eg. physical instruments in the error-prone, real world) and when observations can be made to reduce said uncertainty. I've created a library for MCL in any number of dimensions, so that any number of error-prone factors can be accounted for.

Monte Carlo Localization Library

- benchmarked eight fair ML algorithms on seven credit scoring data sets
- investigated profit-fairness trade-off to quantify the cost of fairness
- published a paper with the results at the European Journal of Operational Research

Fair Machine Learning in Credit Scoring

- Unreal Engine 4 & 5
- 3d model
- detailed texture
- objects and terrains
