Selected work

Analytics, BI and analytical products

Three projects demonstrating governed BI, analytical product design and operational analytics — from semantic modelling and executive reporting through to secure workflow applications. Each is independent personal work, not a client engagement.

Claims Performance Hub

Turning governed Power BI analytics into operational action.

A secure operational analytics application built over an existing Power BI semantic model. Live governed measures feed application-level benchmarking and exception detection, converting analytical signals into a persistent claims worklist with ownership, prioritisation, target dates and case notes.

Capability

Where my experience is deepest

Analytics & business intelligence

Tableau-led dashboard and reporting development, from requirement through to delivered solution. Power BI development across report design, semantic models, TMDL and DAX.

Data visualisation & executive reporting

Information hierarchy, dashboard UX and management information built to stand up to scrutiny in the room where the decision is made.

SQL & data modelling

Queries, semantic models and measures — the structures underneath reporting that stays consistent as it grows.

Reporting rationalisation & MI

Simplifying fragmented reporting: fewer reports, consistent numbers, clearer ownership of what is actually produced.

Experience

Senior analytics delivery in regulated, enterprise environments

Most recently VP Tableau Developer in Compliance Data Analytics at Barclays, delivering and governing enterprise Tableau reporting for Compliance and Risk stakeholders.

My wider career covers senior analytics and business intelligence roles across financial services and other enterprise environments — dashboard and reporting development, visual analytics, compliance and risk analytics, BI governance and modernisation, and reporting rationalisation.

The consistent thread is senior stakeholder-facing delivery: understanding the decision first, then building the reporting that supports it.
