Contracted to September 2026. Open to conversations about future work.
Production data products teams can trust.
An Analytics Engineer who finds the real problem before building the solution. Sixteen years across FinTech, HealthTech and Banking.
What I do
At the heart of the work is data modelling, turning raw data into something a business can rely on, with a clear grain, tested logic and documented columns.
Stabilising a platform already in production
Taking something unstable or inherited, making it dependable, and rebuilding trust in the numbers.
Building an analytics function from nothing
Defining the strategy and standards, growing a team, and setting up something that carries on long after the engagement ends.
My method
Two frameworks of my own, shaped by what actually happens on the ground and written to be remembered when you need them. The 5 Ds of Data Development takes a project from first conversation to production. MAESTRO is the model for the properties a production-grade pipeline needs.
About me
I'm Phil Marsden, an analytics engineer with sixteen years in data across FinTech, HealthTech and Banking, most recently at Birdie, Hokodo and Lendable. I hold a Masters in Mathematics from York. What I care about is leaving a team stronger than I found it, with practices they keep and a function that runs without me.
