Data, end to end.
Data, end to end.
I help businesses go from guesswork to decisions they can trust — collecting, cleaning, modelling and presenting data, all the way through.

THE PROBLEM
You have data. You just can't trust it enough to decide from it.
You have data. You just can't trust it enough to decide from it.
Reports disagree. Nobody owns the numbers. Every question turns into a fire drill. You don't need another dashboard — you need someone to own the whole chain: where the data comes from, how it's cleaned and modelled, and how it reaches the people making the decisions.
WHAT I DO
A complete data function — without the headcount of a whole team.
A complete data function — without the headcount of a whole team.
01. Find & collect the data
Including the first-party data that doesn't exist yet — I’ll go and measure it.
02. Clean & standardise it
One consistent definition across markets, teams and tools.
03. Model & transform it
Reliable pipelines with built-in-validation, so the figures hold up under real-world complexity.
04. Present it
Dashboards and reports built around the decisions they support; not the data that's easy to show.
05. Make it dependable
Clear ownership, refresh schedules and realiability you can plan around.
THE DIFFERENCE
Most data people start at the dashboard. I start at the measurement.
Most data people start at the dashboard. I start at the measurement.
Analytics usually assumes the data already exists somewhere clean. Often it doesn't. I've gone into the field and measured what nobody had captured — turning raw fieldwork into a usable product.
I can create the dataset, not just polish what you already have.
