Here's a DALL-E generated image that tries to capture a few of my hobbies and interests!
While the majority of my work cannot be shared due to it being proprietary to the companies I've worked for, I try to upload projects that I can make public here. Please see the links and descriptions below.
This was a piece of analysis I undertook as part of an application to a Senior Data Scientist role. I received excellent feedback.

SRV Bacteria Predictor
An ensemble model with a Gini Coefficient of 70+ was developed to identify service reservoir assets at risk of ecoli failures to direct manual investigations. Water quality samples are regularly taken from each of the 300+ service reservoirs located across Wales. These samples are analysed and the data uploaded to a centralised database. A legacy model was historically used to identify assets but stakeholders felt its performance had degraded to the point of no longer being fit for purpose. This model redevelopment project included:
- Extensive EDA.
- Data drift analysis.
- 10, 000: 1 class imbalance.
- Low capacity for on-site investigation required minimal false positives.
- Interactive Power-BI Dashboard.
- SMOTE & TOMEK link resampling.
