Data Analyst | Data Scientist | AI Engineer

MSc in Applied Data Science, trained first as a mechanical engineer. I analyse data to support decisions, build models that hold up to scrutiny, and ship AI systems with tests, CI and published results. Everything is public.

Summary

My route into data was not a straight line, and that is the point. I trained as a mechanical engineer (BEng Mechanical and Production Engineering), then completed an MSc in Applied Data Science at the University of Sunderland.

That background shapes what I build. I write analysis for decision makers: every finding has a size, an owner and a stated limit, and every figure reconciles to a control total. My maintenance work starts from the equipment side of the problem, and my RAG system cites its sources because an unsourced answer is useless in a regulated setting.

Right now I am deepening the production side of the craft through two intensive programmes: a Full Stack Generative AI and Agentic AI Bootcamp and a DevOps, MLOps and LLMOps Engineering Bootcamp. Everything I build is public: the code, the evaluation results and the write-ups. I also build websites for local businesses, which means I ship software that real people use.

Data Science projects

Modelling with the decision in mind: imbalanced classification, cost-based thresholds, explanations and drift monitoring. More to come as I finish the next build.
