What I do

Dashboards that show what's happening, why it matters, and what to do next.

I work end-to-end — from data audit and modelling, to tracking rebuilds, to Power BI delivery. The output is always the same: a clear picture of the business your team can act on.

Power BI dashboards

Executive, commercial, and operational dashboards that leadership actually opens on Monday morning.

Data modelling & SQL

Star schemas and clean joins so your reports stay fast, accurate, and trustworthy as data grows.

Tracking & reporting automation

GA4 & GTM tracking rebuilds, scheduled refreshes, Python pipelines. No more manual Monday exports.

Commercial insight

Numbers paired with a written story — what's changed, why it matters, and what to do about it.

Selected work

Featured case studies

Real engagements, real dashboards. Each one shows the problem, the approach, and the commercial impact delivered.

All case studies

Case studies coming soon.

How I work

A clear, repeatable process — from discovery to handover.

  1. 01

    Discovery

    Understand the business, the numbers that matter, and what today's reporting can and can't answer.

  2. 02

    Audit & model

    Map data sources, tracking, and pipelines. Clean the model and fix what's broken at the foundation.

  3. 03

    Build

    Dashboards, tracking, and automated reporting — designed for the people who'll use them daily.

  4. 04

    Handover

    Documentation, training, and a written playbook so the team owns the system after I leave.
