Data Scientist
in the United Kingdom
I'm Brandon Allen, an independent data scientist based in Plymouth, working with organisations across the United Kingdom. I turn your data into defensible conclusions: statistical models, machine learning pipelines and evaluation frameworks in which every result is measured, reproducible and honest about its uncertainty.
Data science as a discipline, not a dashboard
Much of what is sold as data science is visualisation. The discipline itself is harder and more valuable: framing the question precisely, choosing methods whose assumptions your data actually satisfies, quantifying uncertainty rather than hiding it, and designing evaluations that would detect the result being wrong.
My practice combines classical statistical modelling (regression, hypothesis testing, experimental design) with applied machine learning: feature pipelines, model training and selection, held-out evaluation and calibrated deployment. Because I also build AI infrastructure, analysis does not stop at a report; models are deployed as production systems on your own hardware where required.
Everything is reproducible by construction. Analyses are versioned, datasets are documented, and conclusions arrive with their confidence intervals attached, so decisions made on the work can be defended later, to a board, an auditor or a regulator.

Frequently Asked Questions
What kind of problems does a data scientist solve?
Any question where the honest answer lives in your data: which customers are likely to leave, whether a process change actually improved outcomes, what drives cost or demand, whether a model is safe to deploy. The common thread is turning raw records into a conclusion you can act on and defend.
How is this different from hiring an analyst?
Analysis describes what happened; data science quantifies what it means and predicts what happens next, with stated uncertainty. I bring the statistical training to choose valid methods, and the engineering background to deploy the resulting models as production systems rather than one-off spreadsheets.
Can our data stay confidential?
Yes, this is a core specialism. Analysis and modelling run on your own hardware or private cloud, so confidential or regulated data never passes to a third party. For UK organisations bound by GDPR or sector rules this is often the deciding factor.
Do you work remotely across the UK?
Yes. I am based in Plymouth and work on-site across Devon and Cornwall, and remotely with organisations throughout the United Kingdom. A typical engagement begins with a short scoping call, then a pilot analysis on your real data before any larger commitment.
